Thanks for the answers, yeah, that helps a lot!
I still have some other questions:
I tried out an Eolina some time ago, and it was nearly impossible to bend notes on it due to the bi-directional reeds. Is this the same with the Seraphone (because I need the possibility to bend notes as strong as possible!)?
Is there only the flexible tube to play the instrument with? There have been lots of discussions about mouthpieces on this forum and most of us would be lucky about a bigger variety of mouthpieces (flexible or rigid, trumpet-like, flute-like…).
How much would a regular model cost?
Thanks for answering, Quetscher
