For All We Know

1. Song Overview

The lyric is built on an unusually severe premise for a conventional love song: intimacy matters precisely because continuity cannot be assumed. The title phrase is epistemic rather than sentimental. “For all we know” means that the speaker cannot guarantee another meeting, another night, or even the persistence of present experience. From that uncertainty comes a practical argument: do not defer tenderness. The song therefore moves from speculation, through the ritual of parting, towards an explicit demand for love in the present.

What distinguishes it from many separation standards is the absence of a compensating fantasy of reunion. The speaker does not promise to remember forever, anticipate a return, or imagine a secure future. Even the natural world offers no consolation. The image of the “ripple” makes human presence transient rather than cyclical, while the extraordinary formulation “tomorrow was made for some” treats futurity almost as a privilege that may not belong to the two people in the song. The emotional trajectory is consequently not from sadness to hope, but from uncertainty to urgency.

Coots’s musical setting keeps that argument from becoming purely declamatory. The A material is graceful and periodic, with broad sustained notes followed by compact triplet and eighth-note movement. The B and C sections become more continuous and harmonically chromatic. Crucially, the two concluding sections begin with closely related melodic material but diverge harmonically and dramatically. B describes the etiquette of parting; C turns similar melodic material into the direct request to “love me tonight”. The same musical gesture is therefore transformed from restraint into exposure.

2. Form and Dramatic Architecture

The attached sheet gives no rehearsal letters, but the melodic and harmonic design is a clear ABAC, a classification also given in published jazz-standard analysis. The first two bars of B and C are closely related melodically, after which the sections diverge substantially. (jazzstandards.com)

The form is dramatic because repetition does not mean psychological stasis. A1 concerns separation between two people. A2 broadens the issue: perhaps the whole experience is as unstable as a dream or a ripple. The repeated A music therefore acquires a different weight without requiring melodic development. The constancy of the tune throws the changed thought into relief.

B and C are still more revealing. Their openings are intentionally cognate. B is socially restrained: the lovers will resist saying the expected word of departure, and the speaker offers hand and heart. C begins with related melodic rhetoric but abandons decorum for direct appeal. Harmonic divergence accompanies that change. What had been a chromatic passing-diminished progression in B becomes an applied minor ii-V and a chain of dominants in C.

The lead sheet economises notation through its return and Coda structure rather than writing all 32 measures in uninterrupted succession. Analytically, however, the heard form is ABAC. There is no notated introduction or extended tag in this chart, and the final cadence closes on F6.

3. Close Reading of the Lyrics

The lyric’s strength lies partly in how little narrative information it supplies. We are not told why one person is leaving, whether the relationship is established or new, whether separation is voluntary, or whether the feared finality has any concrete cause. That absence universalises the situation while preserving dramatic immediacy.

There is also a carefully controlled movement from modal language to imperative language. “May” and “for all we know” repeatedly qualify what can be asserted. Only the request itself becomes unqualified: love must happen now because the future cannot be depended upon.

4. Lyrical and Emotional Arc

Opening Position

The speaker begins in uncertainty, not despair. The first claim is deliberately conditional: another meeting may be impossible. This distinction matters because the lyric’s urgency depends on not knowing. A certain farewell would produce grief; an uncertain farewell produces a different psychology, one in which every gesture might retrospectively become the last.

The opening also reveals that the separation is immediate. “Before you go” establishes a practical deadline. The speaker’s attention therefore contracts from an indefinite future to the remaining minutes of the present encounter.

Development

B converts abstract anxiety into behaviour. The speaker proposes not to say the conventional word of departure until forced to do so, then substitutes touch and emotional sincerity for verbal closure. The movement into D minor at the centre of the section deepens the sense that a social farewell ritual has acquired private existential significance.

A2 then enlarges the argument. It is no longer merely possible that the lovers will not meet again; experience itself may be dreamlike. The ripple image places the couple within an impersonal flow of time. That image makes the subsequent request in C more consequential because the speaker is now arguing against transience itself.

Point of Greatest Tension

The greatest tension occurs around “tomorrow was made for some”. Lyrically, this is the song’s starkest proposition. The speaker does not merely doubt a reunion but denies that tomorrow can be treated as a universal possession.

Musically, the phrase coincides with A7 and E-flat7sharp11. These chords share the essential dominant tritone, so the second can be heard as a substitute continuation of the first. The harmony seems to turn sideways rather than arrive. It then settles onto D7, beginning the final circle towards Gm7-C7-F. The most fatalistic language thus appears at the point of maximum chromatic dominant concentration.

Resolution or Lack of Resolution

The music resolves. The lyric does not.

The final C7-F6 cadence establishes F unmistakably, but the last words restore the title’s uncertainty. No new fact has emerged, no promise has been made, and no external obstacle has been removed. What changes is the speaker’s response to uncertainty. The opening treats not knowing as a source of anxiety; the ending has converted it into a reason to act now.

The result is acceptance only in a limited sense. The speaker accepts that tomorrow cannot be guaranteed, but does not accept emotional distance in the present.

Central Paradox

The song’s central paradox is that uncertainty produces decisiveness. The speaker cannot make a confident statement about tomorrow, yet that very inability generates an absolute emotional demand in the present.

A second, subtler contradiction lies in the treatment of farewell. The speaker refuses to say “good-night”, but every subsequent image confirms that separation cannot be prevented. Language delays finality while the harmony continues inexorably through cadential cycles.

5. Detailed Harmonic Analysis

The global tonic of the attached lead sheet is F major. There is no sustained modulation away from F. Instead, the song uses secondary dominants, diminished passing harmony, brief minor tonicisation and substitute dominants to create local instability.

The A sections remain strongly related to F despite their frequent dominant chords. B gives D minor the clearest local tonic emphasis. C constructs a long dominant route back to F rather than establishing another independent key.

A1, bars 1-8

The central feature is not harmonic complexity but withholding. Bars 2-4 create an expanded dominant region: G9 moves to C7, then C7 is reapproached through its own ii-V. The phrase therefore spends more time preparing tonic than occupying it.

B, bars 9-16

The most elegant detail is bars 9-11. F/A, A-flat°7 and Gm7 create a bass descent A-A-flat-G while upper voices can move economically. A-flat°7 contains A-flat-B-D-F; Gm7 contains G-B-flat-D-F. D and F remain common tones while the two altered tones resolve by semitone. The chord is therefore better understood as chromatic passing diminished harmony than as a displaced functional leading-tone chord.

Bars 12-14 deepen the harmonic field through D minor. Eø7-A7flat9 supplies a textbook minor ii-V, and Dm is prolonged sufficiently to register perceptually as a local tonic. Yet the tonicisation is brief. The music soon reinterprets Dm7 within the F-major network and begins rebuilding dominant motion.

A2, bars 17-24

The important analytical fact is psychological rather than functional: the harmony does not change when the lyric becomes more metaphysical. The listener hears the same secure syntax while the words undermine the security of experience itself.

C, bars 25-32

C is more directional than B. Beneath its rhetorical urgency lies a nearly continuous dominant chain. Bø7-E7flat9 points to A; A7 implies D; E-flat7 substitutes chromatically for that same A7 function and resolves by semitone into D7; D7 reaches Gm7; Gm7-C7 reaches F.

This is one of the chart’s most consequential distinctions from superficially similar ballad harmony. The chromatic chords are not interchangeable decorations. A-flat°7 in B is principally linear passing diminished harmony. E-flat7sharp11 in C is genuinely tritone-related dominant substitution.

6. Tonal Journey

F major is therefore never genuinely displaced by another tonic. D minor has the strongest local claim because it receives its own iiø-V and a prolonged Dm sonority, but even this remains a tonicisation rather than a full modulation.

The tonic itself is repeatedly recoverable but not continuously inhabited. That perceptual pattern suits the lyric unusually well. F represents not so much emotional safety as the possibility of returning to a familiar frame. Every return is followed by renewed dominant motion until the final cadence.

The ending matters precisely because it does something the words cannot. Harmony answers the question of tonal destination with F6; the speaker’s question about tomorrow remains unanswered.

7. Melody and Prosody

The melody is relatively compact, lying approximately within C4-E5 in common F-major notation of the song, a range also given for a published F-major vocal arrangement. (Musicnotes.com) The expressive interest therefore comes less from spectacular range than from register, duration and the placement of motion against harmony.

The A melody alternates broad sustained notes with shorter arcing figures. JazzStandards’ melodic analysis similarly describes the A material as sustained leaps followed by curving eighth-note movement, while B and C become more flowing. (jazzstandards.com) This distinction is dramatically useful. The title phrase sounds spacious enough to accommodate reflection, but the quicker figures towards the ends of phrases give the sense that thought is gathering momentum.

Triplets are particularly important. They soften the square metre and bring the melodic line closer to conversational speech. Around phrases concerning meeting again, the sweetening of the moment and the stream image, the triplet figures avoid a rigid declamatory character. They also give singers considerable scope to place syllables behind or ahead of the beat without breaking the contour.

The A sections repeatedly begin from a pickup. Consequently, significant words do not all fall on blunt downbeats. The line sounds spoken into the bar rather than announced from its beginning. That is valuable for a lyric whose argument is intimate rather than public.

B changes the prosodic character. “We won’t say…” is more syllabic and continuous. The chromatic bass descent beneath it allows the melodic line to preserve composure while the accompaniment becomes less stable. This creates one of the composition’s best examples of expressive counterpoint between layers: the singer can sound controlled while the harmony quietly acknowledges what the words are resisting.

The repeated melodic opening of C is structurally crucial. “So love me tonight” initially resembles B’s opening gesture. The listener recognises the shape before fully registering that its harmonic continuation has changed. Bø7-E7flat9 beneath the C continuation gives familiar melodic material a more pressing, exposed quality.

The closing phrase gradually relinquishes that pressure. D7 moves to Gm7-C7, and the final melodic arrival is on the tonic F over F6. After a lyric dominated by conditional verbs, the melody is permitted an unequivocal terminal pitch. The added sixth in the accompaniment prevents the cadence from becoming overly monumental.

Prosodically, the most important words should not be identified merely by pitch height. “Tonight”, “tomorrow”, “never” and the recurring word “know” derive much of their force from harmonic context and duration. The title word gains meaning through recurrence: each occurrence sounds musically familiar, but what the speaker now understands about uncertainty has changed.

8. Word, Melody, and Harmony: Key Moments

9. Historical and Cultural Context

J. Fred Coots and Sam M. Lewis wrote “For All We Know” in 1934. A surviving copy in the Mississippi State University sheet-music collection identifies Leo Feist, Inc. as publisher and confirms the song’s 1934 publication. That source also shows that the original song contained an introductory verse before the familiar chorus. The attached jazz lead sheet omits that verse and begins directly with the chorus. (scholarsjunction.msstate.edu)

Contemporary jazz-standard documentation credits vocalist Morton Downey with introducing the song on his radio programme. It quickly entered the commercial dance-band repertory. Hal Kemp’s orchestra, with Skinnay Ennis singing, reached number 3 in 1934, while Isham Jones’s recording with Joe Martin reached number 16. (jazzstandards.com) The song therefore belongs initially to the interwar American popular-song economy of radio, dance orchestras and sheet music rather than to the jazz repertory in the narrower modern sense.

Its lyric is well suited to that period’s popular ballad language but is more severe than its elegant surface initially suggests. There is no elaborate narrative and little period-specific vocabulary. Its argument rests on perennial concepts of departure, time and uncertainty. That abstraction helped the song survive changes in performance idiom.

The King Cole Trio recorded it in New York on 22 March 1949, with Cole on piano and vocal, Irving Ashby on guitar, Joe Comfort on bass and Jack Costanzo on percussion. (jazzdisco.org) JazzStandards credits Cole’s recording with returning the song to mainstream attention fifteen years after its composition. (jazzstandards.com) Whether described as revival or rediscovery, the recording is an important point in the song’s transition from 1930s popular repertory into the post-war jazz-standard canon.

The tune subsequently attracted both singers and instrumentalists. Paul Desmond developed a particularly sustained association with it, including performances with Dave Brubeck and later with Jim Hall; jazz discographies also document interpretations by Stan Getz and Cal Tjader, Benny Carter, Wes Montgomery, Grant Green, Cedar Walton and Wynton Marsalis. (jazzstandards.com) Its survival is therefore not primarily a matter of nostalgia for a 1934 hit. The ABAC form, strong melody, compact dominant logic and chromatic interior sections give improvisers enough structure to reinterpret it without obscuring its identity.

The song should not be confused with the unrelated later “For All We Know” associated with the 1970 film Lovers and Other Strangers. The Coots-Lewis composition is the 1934 standard analysed here. (jazzstandards.com)

10. Significant Interpretations

The contrast between Cole and Holiday is particularly instructive. JazzStandards specifically singles out both vocal performances while noting their very different instrumental backgrounds. (jazzstandards.com) Cole’s small-group environment allows the song to sound almost conversational. Holiday’s orchestral frame magnifies the distance between public arrangement and private utterance.

Brubeck and Desmond demonstrate the opposite process. Once the lyric disappears, the delayed cadences, chromatic bass motion and B/C contrast must communicate the architecture unaided. The song withstands that removal because the tune and harmony already possess a coherent dramatic sequence.

11. Place in the Jazz Canon

“For All We Know” endures because it occupies a useful space between harmonic familiarity and structural individuality. Its basic materials are accessible to improvisers: secondary dominants, ii-V motion, relative-minor tonicisation and circle-of-fifths resolution. Yet their arrangement is sufficiently distinctive that a player cannot simply treat the tune as an interchangeable 32-bar ballad.

The ABAC form is the first essential point. A player expecting AABA can easily lose the final section because C initially recalls B but then diverges. This similarity is precisely what makes the form elegant and what makes inattentive improvisation hazardous.

The second issue is functional hierarchy. G9 in A is genuinely V/V. A-flat°7 in B is primarily chromatic voice-leading harmony. E-flat7sharp11 in C has a much stronger substitute-dominant interpretation. Treating all three as generic “outside” chords erases the logic that makes the progression easy to hear.

The third issue is the D minor region. Eø7-A7flat9-Dm is not merely a string of altered chords; it produces the principal temporary tonicisation of the song. An improviser who hears D minor locally can build a phrase across the cadence rather than changing scales mechanically at every chord symbol.

The tune is also flexible across performance styles. Recordings range from 1930s dance-band balladry to Cole’s trio, Holiday’s orchestral setting, Brubeck’s extended quartet performance and later soul and post-bop treatments. (jazzstandards.com) That breadth reflects the strength of the underlying form rather than dependence on one canonical arrangement.

For improvisers, the real task is therefore to hear long spans: G9-C7 as expanded dominant motion, bars 9-11 as one chromatic bass gesture, bars 12-14 as a D minor episode, and bars 26-32 as a dominant chain whose goal is the final F. The chord symbols become considerably easier once those trajectories are heard.

12. Interpretive Considerations for Performers

The lyric benefits from restraint because its language is already extreme. A singer does not need to make every reference to “never”, “last” or “tomorrow” sound tragic. If those words are delivered conversationally, the implications can emerge from the harmonic setting. Excessive pathos too early can leave C with nowhere to develop.

The title phrase should remain flexible. Its first appearance is speculative, the second follows a much more intimate B section, and the final appearance comes after the direct appeal and the chromatic dominant chain. Repeating identical inflection on all three occurrences loses part of the lyric’s architecture.

The A sections tolerate rhythmic elasticity, especially around the triplet figures, but their long notes should preserve the sensation of suspended thought. Over-filling them with ornament can obscure Coots’s contrast between spacious openings and more active cadential figures.

The bass descent F/A-A-flat°7-Gm7 is worth preserving even in substantial reharmonisation. It gives B a clear physical trajectory and makes the move into Eø7-A7flat9 feel inevitable. Replacing those chords with unrelated colour harmony may produce sophistication at the cost of form.

Similarly, the distinction between B and C should remain audible. If both sections are reharmonised with the same generic chromatic substitutions, the dramatic escalation into “love me tonight” is weakened. C benefits from a stronger applied-dominant profile than B.

The A7-E-flat7sharp11-D7 sequence offers room for alteration because the tritone relationship between A7 and E-flat7 is already structurally explicit. Extensions, altered fifths and upper structures can intensify the passage without destroying its direction, provided D7 still arrives as a clear dominant of Gm7.

Instrumentalists should retain the melodic identity of the beginnings of B and C. Their resemblance is not accidental filler; it is part of the composition’s rhetoric. The second occurrence becomes meaningful because the listener recognises the first.

At very slow tempos, the song becomes more existential. Chromatic passing harmony can be savoured, and the distance between phrases acquires dramatic weight. At a medium ballad tempo, the lyric sounds less fatalistic and more urgent, while the form’s circle motion becomes more apparent. A light medium swing can reveal how rhythmically viable the tune is beyond its customary torch-song treatment, as instrumental interpretations have demonstrated. (jazzstandards.com)

The final F6 should not necessarily be inflated into a grand emotional conclusion. Its significance lies in its simplicity. After the dominant sequence, a clear tonic is enough. The words have not solved the problem that began the song.

13. Final Reading

“For All We Know” is fundamentally about the ethical and emotional consequence of not possessing the future. Lewis does not ask the speaker to predict catastrophe. The lyric is more disciplined than that. It repeatedly insists only that tomorrow cannot be guaranteed, then asks what one should do with the present under those conditions. The answer is intimacy without postponement.

The speaker understands transience with unusual clarity but does not fully accept separation. Refusing to say “good-night” is a small act of magical resistance, as though withholding the word might delay the event it names. Yet the speaker’s imagery continually defeats that impulse. Minutes expire, dreams dissolve, ripples disappear into moving water. The lyric is compelling because it allows emotional resistance and intellectual recognition to coexist.

Coots’s harmony keeps the composition from sinking into unqualified sentimentality. The opening tonic is repeatedly displaced by dominant function. B’s chromatic A-A-flat-G descent undermines its outward composure, and the D minor tonicisation gives the middle of the song a temporary darkness without transforming the entire piece into minor-key lament. C intensifies rather than simply repeats that process. Applied dominant harmony accumulates beneath the direct appeal for love.

The melody is equally controlled. Its range is modest enough for speech-like intimacy, and its combination of sustained notes and triplet motion permits an interpreter to move between reflection and urgency without changing the composition’s basic character. Most importantly, repeated melodic material acquires new meaning from altered text and harmony. The melody does not have to announce psychological development because the form makes the listener hear familiar gestures differently.

The final cadence is therefore both satisfying and insufficient. C7 resolves to F6; the tonal problem has been solved. The verbal problem survives unchanged. The title phrase still means that neither person knows what follows. What the song has achieved is not knowledge but a changed relationship to ignorance: uncertainty has become the reason for emotional presence rather than an excuse for hesitation.

That distinction is why the song continues to reward radically different singers and improvisers. It can be intimate, elegiac, lightly swinging, orchestral or harmonically exploratory without losing its premise. The argument is embedded not only in Lewis’s words but in Coots’s form: leave home, postpone arrival, revisit what seemed familiar, intensify the route back, and finally arrive somewhere the lyric itself cannot guarantee.

The central artistic insight is precise: the music can resolve because the future cannot.
