Talk:List of aerophones by Hornbostel–Sachs number

Comment
From my personal use of a side blown trump, I must dispute the assertion that the lips are involved in the process. My instrument is made of cow horn: all pitch & tone variation is made inside the mouth, using the tongue & throat positions, with or without a hand over the end hole. It is a most versatile instrument.AptitudeDesign (talk) 00:40, 4 March 2013 (UTC)
