Programme Note

Tesserae B was written for Judith Pearce and Ronald Lumsden, and first performed by them in December 1970 at the Wigmore Hall. The work is one of a group of pieces based on various transformations of a 19th century English hymn tune, which is however not used in anything like its original form. Instead small elements of musical material derived from it are used in constantly changing juxtapositions. Hence the title, for tesserae were small fragments used by the ancients in games as counters or pledges, and the term is also applied to the constituent parts of a mosaic.

Inclined ligatures are used to indicate various degrees of accel. or rit. The barbed ligatures show the relation between such changes of speed where values above  are used. Forking ligatures indicate changes of values between  and Ž of the prevailing metronome instruction. Where no barlines are used, the character of playing is of an improvisatory style, and the pause signs are used to indicate in a general way the distinction between relatively long breaks, and shorter ones having the character of "breaths" of caesuras.
