The chords are: 4 x F- / 4 x Db7 / 4 x D- / 4 x F-
So, Cantaloupe island is only three chords, F- D- and Db7
- For F- and D- , we can use the minor pentatonics or the dorian scales for each chord.
- For Db7 , we can use Db mixolydian, or Ab minor pentatonic or Ab dorian.
- For the solo, either use a straight Db7, or also a Db7+4 (lydian dominant) chord/scale (Db Eb F G Ab Bb Cb Db)
Or
Here’s a 1-scale approach derived from the melody:
The entire melody of this song is made of the f-blues scale (F-Ab-Bb-B-C-Eb). consequently you might stay with it while improvising. of course there are certain ‘clashes’ with some of the chords if you do this:
- When it comes to Db7, we need to skip the C note (being the ^7 of Db7) or replacing it with Db note
- When it comes to D-, there is a certain tension if you continue to play the f-blues scale – but it might work (alternatively you might switch to the d-blues scale for these 4 bars).
