I was curious about the name "glissotar" (less self-explanatory than the in-development glissoflute and glissoboe) but it appears to refer to the Hungarian Tárogató https://en.wikipedia.org/wiki/T%C3%A1rogat%C3%B3
When singing, it often sounds bad to slide between notes. Why is that? Music is rather discrete, rather than continuous— we like notes. But maybe that’s just what we are used to?
Here's a playlist of songs composed for glissotar: https://www.youtube.com/playlist?list=PLHQMlBq9OKeXINkPCOrLy... (found at https://sonus.foundation/en/page/show/call-for-scores-new-pi...)
