I did #xylophone (easy, you have to make one if you haven't tried it yet) https://exode.me/w/fuTBAecw6k67zz53ZcoWxe
Now a #whistle!
I'm an expert (no), tell me how you did it yourself!
1st try in *Viburnum opulus* (Sambucus or lilac are easy to use too) ⇒ wood too soft for clean bevel but it works.
2nd try: I drill ⌀10 in *Prunus padus* and then sand to make a nice blind pipe.
