gpsgamelan.py is ok, but i want real music - use 12 major keys with 10 chords

Continuing to have a great time with Python on the N900. I'll have to post later about how awesome it is to run N900 Python aka PyMaemo scripts  from a Terminal.app window on my Mac edited in Aquamacs using ange-ftp (or whatever it's called in the 21st century).

Anyhow came up with gpsgamelan.py which is a modification of the script from latlongsound.py to play gamelan (indonesian scale) music (using the code from PyGSoundTestTest_3.py from Matthew Brown, thanks!) based on the jitter from GPS Lat/Long (10 different sounds based on latitude and another 10 different gamelan sounds based on longitude)

Here's what it sounds like (short video from flickr):

Not so great sound. My next idea is to play more pleasing music

• e.g. for each neighbourhood, pick a major key (there are twelve possible major keys in Western music AFAIK)
• based on the latitude, play a major chord (one of 10 possible)
• based on the longitude, play a minor chord (one of 10 possible)

My guess is this will produce more melodic and pleasing sound
