When I first saw this video, I immediately wanted the little green keyboard that Masaki Kurihara plays. It looked like I could carry it in a backpack on my bicycle or at the campgrounds at Winfield, and I would not need to find an electrical outlet or a USB port. After some searching, I determined that it was a Suzuki Andes 25F, a sort of panpipe with a keyboard. Unfortunately, the ones available for sale then were too expensive to consider. I recently checked again and found much better prices. The best was at a Japanese shop affiliated with Rakuten Global Market, which is where I ordered it. Placing the order was a bit complicated but not too tedious, and it arrived fairly quickly once it was shipped.
It has a two-octave range, from F to F. I frequently play in D, A and E, and a few more notes at the low end would have been extremely helpful. Still, there are plenty of tunes that fit well on it. The keys are smaller than regular piano keys. People with small fingers have an advantage; those with larger hands, like me, will find that it takes practice to avoid playing two notes simultaneously with one finger. The lower octave has a pleasant sound, but the upper octave gets shrill, and I avoid playing the highest notes. Unlike most flute-sounding instruments, you can play chords on it. Thirds sound good; fifths, triads and octaves can be unpleasant. Also, the more notes you play at once, the more breath it requires. Glissandos are easy.
The biggest problem is that there is no good way to hold it. There’s no handle on the instrument itself, no strap to slip your hand into. There is an indentation on the angled side that I think is intended for a hand hold, but it feels awkward and your arm soon gets tired. There’s a neck strap, but it isn’t secure. I’ll have to think about this and see what I can devise.
Would it be possible/beneficial to wear it strapped across your chest, left shoulder to right hip? Perhaps using a guitar strap and something screwed into the bottom of the instrument?
