So I just returned from China. The Chinese tuning caught me unsuspecting. While I was there, I had an opportunity to play a pipa and a xiao. The pipa is four string lute, tuned A D E A. Which seems awefully weird. Well I dug into it and figured out how to play the rhythm changes on it, but they don't sound very good on the instrument. Even thought the fingering is very easy. So I did some google it turns out the frets aren't at all equal tempered. Chinese and Western Music Then I got to talking to my wife she said that when she plays Guzheng, that there are many chords la re mi la, do fa so do, and re so la re. IE a suspended second chord. Looking back at the pipa indeed that is how it is tuned. do fa so do, then looking at the link it turns out the fifths and fourths are indeed perfect and the octave is not! So my question is how do you make brass arrangments for these types melodies I have never been a big proponent of the suspended second or fourth, and don't know how they would resolve However I think they sound better in the Chinese tuning. I think horns are in pretty good shape intonation wise, since the fifths could easily be perfect, maybe the valve slides need to be adjusted, but other wise Any suggestions?
