This is a flute: a Fliphead Flow model, which is played vertically, a Nuvo Student Flute, and a LexaLive mouthpiece created and sold by a person named Martin Educciman (purchased directly from him). I couldn't find any videos of someone playing the exact same model, but please see the following video as a similar example: https://youtube.com/shorts/JFMXiSKZ_pI?si=PnEByyHuLXTSUJjs A hook for the right thumb has been attached to the Nuvo flute to allow it to be held vertically. Because of this, it no longer fits in the hard case, so it will be sold with a soft case. Thank you for looking.
