Learning Task 3: Amabahan is a kind of vocal music of Mindoro, with seven- syllables
and it has rhymes at the end of the line. In your notebook, create
Ambahan that tells about love and suggest or notate the tempo and
rhythm for it.​

i think this is true

it seems to me that yes they solo on the chord changes.  coltrane for sure solos on the chord changes. instead of changing scales, they use a different method over the chord changes. this melody is very  unique but may often times even be considered simple, which is quite common in this modal  type. for example, there are changes from the key of minor to major in this piece, which makes it  unique in its own way.
