Testing extendable telescopic flutes! | Team Recorder

Instrument inventor Mauri Meronen/TeleTunes sent me a selection of telescopic flutes - extendable whistles! And they are AMAZING! But do they work? How are they tuned? And can I mess around with them a bit? (yes) Order them on the TeleTunes Etsy: Note: the square designs are currently for sale, the hexagonal designs are still in the invention stage ;) // timestamps 00:00 Intro 00:22 Square flute 01:28 Hexagonal flute 02:50 Spiral flute 04:24 Double flute 06:03 CAN I ASK YOU A QUESTION? 06:48 Does it change the pitch/tuning if you don’t fully extend it?? 09:18 Can I play them closed? ////// Website: Tiktok / instagram / twitter: @team_recorder //// ONLINE COURSE!
