Chordal pattern means is provided for blocking and for selectively opening a plurality of the air passages in predetermined chordal patterns. A keynote selection means is provided for manually positioning the tone chamber body and one of the tone chambers therein in registry with one of the air passages of the valve block in order to select a keynote for the predetermined chordal pattern. Cross-indexing means, for selecting a plurality of notes in a chromatic scale and for activating the selected notes, is provided by the spacing of the ports, the spacing of the passages, the pattern of open valves, the relative positioning of the tone chamber body with the housing to select a keynote for the selected chordal pattern, and the resultant registry of a plurality of the tone chambers with a plurality of the open valves.
The method includes manually selecting one of a plurality of predetermined chord patterns, manually selecting a note from a chromatic scale for the keynote of the selected chordal pattern, and cross-indexing the selected chordal pattern with the selected keynote to select a plurality of notes in the chromatic scale which correspond to the selected chordal pattern of the keynote and to activate a plurality of tone-producing chambers corresponding to the selected notes.
