Interplay (Bill Evans)


1 The grid
- Part : interplay.PNG
- Medium blues, tempo 110 bpm. 
- We play it using a lightly simplified grid  : no Bbm6 on measure 2, Fm6 all the way from measure 1 trhough 3 :

Fm6      / %        / %         / Fm6   F+7b9
Bbm7     / %        / Fm6       / Ab7
Gm7b5    / C7b9     / Fm6 Dm7b5 / CM7   GM7


2. Analysis
Interplay is a blues in F minor.

I        / %        / %         / I     V+ of
IV       / %        / I         / V of
II       / V        / I   VI    / bVI    VMaj


  • F+7b9 = relative dominant of Bbm7, it is a blues cliché. Why aug not 7?
  • Ab7 = tritonic substitute of D7, relative dominant of Cm7b5
  • Gm7b5 / C7b9 / Fm6 = II V I in Fm
  • Last two measures are an odd Fm turnaround ending on VMaj7

3 : Arrangement :

One grid each :
- Intro : bass + guit
- Piano Theme
- Winds theme
- Solos : piano, flute (guitar comping), trumpet (piano comping), guitar.
- 4/4 : 2 or 4 grids. Battery should gently bring back the softer dynamic before the theme.
- Winds Theme
- Piano Theme
- Outro : bass + guit

Finale on the first measure ad lib.


4. Solos 
  • One first possibility is Fm blues all the way through.
  • And of course you can arpeggiate all chords.
  • turnaround : Fm or F7b9  can be used trhough both measures of the turnaround.
  • measure 4 : F+7b9 : whether play :
    • A diminished arpeggio.
    • F alt  = Gb mel.minor.
    • Bb harm.minor (but without actually playing the Bb, in order to preserve the resolution on the next chord Bbm7).
  • Measure 10 : V of minor II-V-I is Valt (Caug/C7b9) : play C altered scale with 9d and 13b, do NOT play 2 or 6.
  • Tonal scales for each chord : ???
