R. Carlos Nakai and William Eaton collaborated on 'Carry the Gift' (Amazon.com). On track 9, 'Remember when there was water', the flute follows a simple scale (41222) that is easy to play on most flutes.
Which overlaps the bottom half of the Greek Phrygian scale (1222122).
Minor Pentatonic scale (32232) shifted up a Major 3rd can be found as a subset of the Phrygian scale.
Many scales are found inside other scales. Sometimes a few notes are better than more.
