I have found that inlays do very little to the texture of the sound. I’ve broken inlays and the flutes played no differently. I’ve played on flutes with the inlay totally knocked out. The sound was a little bit fuzzier; that’s all.
I have flutes made by Yamaguchi Shugetsu (Nara), the Kôno family (the deceased father and both sons), Ichijô (Osaka?), Okamoto Chikudo (Okayama?). David Brown (Aus.), and some others I don’t know who made them. My favourite no.1 most used 1.8 flute is one that Tom Deaver made me. My 2.7 (G) is totally without ji, and my 3.1 shaku length flute is virtually a true ‘ji-nashi’ flute, with only small dabs of ji in three places. Its ‘ro’ is F. It is very responsive and easy to play considering its length. Being ji-nashi, it is very light in weight too. It was made by a fellow named Yamaguchi Shugetsu, who lives in Nara.
My longest flute is a 3.6, totally ji-nashi, made by my dear friend, Kurita-san. It is a joy to play. It is the most demanding flute to play. It is really really hard to play. But it is wonderful, in part because with effort it is in tune and can produce all the notes and sounds needed to play my favourite honkyoku. As implied by it’s length, it is exactly one octave below a standard 1.8 shakuhachi, a very low D.
I have four others by Yamaguchi, a 1.1 (F), a 1.3 (G), a 1.9 (D#), and a 2.7 (G). All play very well. I have yet to play a really long flute (over 2.6) that I thought was better than the ones I’ve seen of Yamaguchi. I have played a fair few by Miura Ryuho, which I have seen in the USA, and more recently those of my students who have purchased them while studying in Japan. I think that they are exceptional flutes. I recently acquired a new 1.8 by Tom Deaver that I am thrilled about. It will replace my primary 1.8, which was also by Tom Deaver. It has many of the qualities of the Miura flutes I’ve played on, and then some. It’s price was also much less. I also recently bought a 2.2 (A#) by Tom Deaver. One of the many joys of being a professionaly shakuhachi player is not really having to have an excuse to buy another shakuhachi, even one with as obscure length as a 2.2!
My new ‘fat’ Deaver flute projects well, which is important when performing for anything other than the smallest audiences, especially with other musicians. Plus it is as mellow as any flute I’ve played. I also have 1.8, 2.1 and 2.4 Gyokusui flutes (made for me by the deceased Gyokusui elder in 1972-1973) which have that mellow quality. These flutes are wonderful for honkyoku.
I have flutes made by Gyokusui (son) and a 2.0 by Gyokuzan (younger son of Gyokusui), and a 1.7 by Okamoto Chikugai. I like all of these flutes. Finally, I use ones made by Australian maker David Brown. The best is to try lots of flutes by many makers, if only to appreciate your own flute all the better. More likely, you might find a few flutes that are not better or lesser than your flute, just different. Trying to compare some flutes is like comparing kaki with nashi…
