I can see that shamisen traditions can be a touchy subject and is full of personal interpretation, but just for fun I took the risk of fluffing some feathers and stepping on some toes, and made a little summary graph. Just to make sense out of it all, this lists key musical traditions (primarily, what kind of music the practitioners were playing) and some notable performers (sorry to anyone whom I’ve forgotten!).
Traditions in italics are “legacy” traditions. This may be a hard to define concept, but one criterion could be that there are no original compositions being added to the key repertoaire of the tradition.
This is just the first sketch. Any errors or omissions should be attributed rather to my weakness of knowledge rather than strength of opinion. There is very little science behind this. I haven’t done any additional research or studying for the graph, it’s just my personal impressions and recollection of the things I’ve read and heard in the last month or two.
Some notes & discussion:
Influence of rock is prevalent. There is also a strong connection to contemporary music on nagauta shamisen, but the arrow is forgotten here. I’m not very familiar with contemporary japanese music, so here japanese rock & metal & pop was seen just as a part of the western rock tradition.
The other mainline of contemporary western music, tekno, doesn’t seem to be represented in shamisen. No surprise as they have not really used any acoustic instruments.
Has minyou had a notable influence on shamisen fusion? Is shamisen fusion something that’s possible to define as a distinct genre?
Are there any significant traditions behind contemporary shamisen that I missed in the picture?
