Due to the Corona problem, I can't get any thin-walled aluminum tube at the moment. Therefore, I have pimped my old and very much used PVC resonance tubes with a new type of flap.

The new flaps are printed from flexible plastic with a hole "too small" by about 0.1 to 0.2 mm. Therefore, they adhere very well to the shaft after sliding on, but can be aligned and positioned as desired.
I also managed to make this solution foldable. Due to the magnetic coupling, the shafts reconnect by themselves after splitting.

The last Friedman etude!

books that a musician should read.

Learning the vocabulary of jazz is one of my favorite -- and, I would argue, most rewarding -- things to do in the practice room. Just like human language, jazz vocabulary allows us to musically understand one another, know how to react to one another, and keep ourselves from saying something stupid. From Monk-ish quirks to the pentatonic idiosyncrasies of Coltrane, jazz history is, in many ways, synonymous with jazz language -- you can see the evolution of the music, the cultural influences, the “family tree” of players, etc.
