Contentstaken from the introduction of Colour Piping Book 1:
'Colour Piping explains how to play the descant recorder, but there are various others: the treble and tenor, the bass, which is the largest one of all, and the sopranino, the smallest recorder.
Adult and young students can see by the use of colours the exact fingering for the recorder and are thus able to learn the notes within a few hours. If a note is momentarily forgotten there is no need to refer to a book and waste time in looking up the passage which deals with it. One need only glance at the recorder to be reminded of the correct fingering.'
