Hi JC,
I read this thread and wanted to clear up a few things. Iâm not sure where David is getting his information, but it doesnât jibe with my experience. Iâve been studying shamisen for over 20 years, and have played nagauta, jiuta, minâyo, Tsugaru, and Okinawan music, and have different shamisens for each of those genres.
Generally for minâyo, they use a chuuzao (neck of medium thickness) but this varies depending on the region and particular piece. Minâyo from Tsugaru and some other parts of the north use a Tsugaru shamisen, and then there are some very âurbaneâ minâyou that use hosozao to get a different sound, but in general minâyo is associated with chuuzao.
The notation most widely used for both minâyo and Tsugaru is bunka-fu, the sort Kyle uses in his videos. The basic techniques for both are the same, but Tsugaru uses a bunch of extended techniques as well.
Lastly, yes, you can play other types of music on a minâyo shamisen. You can play any scale imaginable since there are no frets, but chords are a bit of a challenge.
If you are looking for an instrument, and are concerned about the cost, the hosozao shamisen is the cheapest and most available used instrument out there. You can play anything on any type of shamisen, in the same way that you can play classical guitar pieces on a folk guitar, but of course each type is specifically made for the music it is meant to play. For a beginner, in my opinion, it doesnât make a huge difference. The biggest factor is how much work you put in learning the instrument.
I hope that helps clear some things up for you. Feel free to keep asking questions.
