A new Flatsax design Bb Mk10

I ve returned to the Flatsax to improve its design, going back to the more compact Bb Flatsax. I started designing these instruments in 2018 (both the Bb and lower F sizes). The tuning of the upper octave has been tricky but this latest version is sounding great and is easy to play. It s compact and light. Materials required are 3mm plywood, 12mm x 12mm pine (or other suitable wood) and a 44mm length of 12mm OD, 8. 5mm ID aluminium tube. It uses a soprano sax mouthpiece. I will soon make the DIY plan available and make more videos featuring this instrument. A detailed plan will be included in my forthcoming eBook My journey with winds covering 50 years of wind instrument designs.
