[Jacob Fournel]

Dear Quetscher,
Do You mean smaller in length or in width ? The “black” keys are smaller in width but the white keys have the same dimensions. We choose this new ratio between white and black keys to have both a quite Small instrument and a 45 notes keyboard.
Were’s no problem about double tonguing and chord playing, the Seraphone works like a mélodica and the’s no loose of air.
