These Cretan tunes run together in long, hypnotic medleys. Having never listened to this music until recently, and never having tried to play it before today, I wasn't sure what would happen but within a few minutes of trying to play along with the first tune on the album - called Esvis aeras to keri (sp?) - I was playing along with it! The time signature and rhythm may be different, but it was definitely using the D major scale, although it wanted to resolve to B so maybe it was B-Aeolian? (see recording above). Looking forward to delving deeper into this album of Cretan music.
My search also uncovered some interesting Bal Musette and Middle Eastern gems, so I hope to cover those in future posts.
