Keep your ears open
This sample pack of a jaw harp was sent by Eugene Vlaskin to the FreePats project, on February 2018:
I recorded this sample pack in autumn of 2017 in the North West of Sakhalin (in Nekrasovka) with the aid of Michail Chayka (a Nivkh musician who played jaw harp) and his mother N.K. Chayka. We used school sound equipment for this recording, so the quality is not very good but after processing in Audacity it seems to me good enough.
