The Thumbport is a revolution in holding the flute. By providing additional support and improving the balance of the instrument, it reduces strain and stress on the hands, and allows for greater freedom in finger movement. Simple to clip-on and doesn’t scratch or otherwise damage the finish of the instrument. Supplied in a cloth pouch. The Thumbport II has a lower default angle for the thumb. It’s a little thicker and more rigid, has less contact with the flute and its extension arm is a little shorter (when attached to the flute, it may go into the case easier for some). The end of the extension has a more rounded shape. Also available for piccolo. The Fingerport index-finger rest is also available. Recommended by William Bennett, Emily Beynon and Wissam Boustany, amongst many others.
