“Impressions” is a John Coltrane composition first released on his 1963 album Impressions, recorded live at the Village Vanguard. It uses the same form and modes as Miles Davis’s “So What,” and its melody is often said to be inspired by a passage from Morton Gould’s “Pavanne.” Coltrane played it at blistering tempos, making it a showcase for modal improvisation.
The form is a 32-bar AABA: 16 bars of D Dorian, 8 bars of Eb Dorian, and 8 bars of D Dorian. The melody is built from stepwise motion within the mode. It’s typically played very fast.
Section by section: in the D Dorian sections, avoid running the scale up and down; instead, use pentatonic scales built on D, E and A, intervals of fourths and short motifs that you develop. When the bridge moves to Eb Dorian, make the half-step shift clear by targeting Gb or Db. Coltrane often “side-slipped,” playing briefly a half step away from the mode and then resolving back, which creates exciting tension.
Practice slowly with a drone in D, then in Eb. Practice switching between the two modes every eight bars. Gradually increase the tempo.
Transposing tip: Bb instruments read it in E Dorian and F Dorian, Eb instruments in B and C Dorian.
Practice checklist for the Impressions Lead Sheet PDF: play the melody from memory, play roots through the form, play guide tones, improvise one chorus of chord tones only, and finally record yourself soloing over a play-along. Listening back is the fastest way to spot what to fix next.
Memorizing the Impressions Lead Sheet PDF: learn the form in sections, not all at once. Play the first eight bars until you can do them with your eyes closed, then add the next section. Within a week or two you won’t need the page at all, which is the real goal of any lead sheet.
Is it hard to play? The harmony is simple, but sustaining interest at fast tempos is challenging. Recordings to study: Coltrane’s Impressions album. Learn more about the composer on John Coltrane’s Wikipedia page, and find more modal lead sheets on Minedit.
