This sequential listing contains blank entries to allow for possible later additions, especially for works written during Truscott's early years about which information is sketchy. A certain number of these early works were destroyed (including several piano sonatas from the 1930s) but it has not been possible thus far to quantify precisely what. The datings for several works from all periods is still conjectural. In general, I have used the date of completion in determining the sequence, especially in light of the composer's frequent false starts at pieces. This generally governed the composer's own ordering of the numbered piano sonatas (e.g. no. 11, begun in 1950 in between nos. 4 & 5, but not completed until 1964, and Piano Sonata no. 8, the First Clarinet Sonata & Piano Sonata no. 9, begun in that order but completed in the sequence: First Clarinet Sonata, Piano Sonata no. 8, Piano Sonata no. 9). Where substantial fragments left unfinished are included, I have used date of commencement (usually as that is the only known date anyway) since very often work on these pieces was effected in one spell from the start.
