Imams

This morning before dawn, we heard the imams calling quite clearly. There is one in particular that is loud and clear and has a nice voice and an interesting tune. The first three notes are like E, D and C, but he ends the phrase with a D# slightly flat and an E slightly sharp, and the final note like a low B slightly flat. These are strange notes to the western ear, but they are true notes in some eastern scale, and they are sung exactly the same every time.
My electric piano, according to the manual, has a function for tuning the keys to Indian scales, but it doesn't work, or doesn't work on this particular model. I should stop in a music store sometime and see what kinds of harps or un-fretted stringed instruments there are that I could experiment with. Not that I have time for such explorations.
