Catalogue Numbers

Only a minority of Tchaikovsky's compositions were published with Opus Numbers. However, there are two other systems of numbering his works, both of which take into consideration the composer's musical and literary works:

• TH number (TH) — as used in: Alexander Poznansky & Brett Langston, The Tchaikovsky Handbook, vol. 1 (2002). This is the main system of numbering used throughout this website.
• ČW number (ČW) — as used in: Polina Vaidman, Lyudmila Korabelnikova, Valentina Rubtsova, Thematic and Bibliographical Catalogue of P. I. Čajkovskij's Works (2006), and in: P. I. Čajkovskij. New Edition of the Complete Works (1993–date).
