Related to my earlier posts, I wanted to also show at the very least one resource for finding kantele tunes online: the digital archive of Finnish folk tunes. The tunes have been collected at the end of the 19th century by the Finnish Literature Society and later digitalised by the Department of Music at the University of Jyväskylä.
You can search the tunes with the Finnish words you want to be included or the parish where it was collected, for example. Perhaps you want to play something from a region where you have some connection. Note that you may need to download a plug-in for SibeliusScorch to see the score and listen to the MIDI. You can find instructions on the webpage for that. If the plug-in does not work, try different browsers (at least Safari seems to work).
The archive has also been used musical data mining research at the university of Jyväskylä. You can, for example, see which regions feature more drinking songs..The data also shows that the proportion of songs in minor key is higher in eastern Finland than in western Finland. No wonder we are so melancholic in the east..
