This is my first ever composition for the duo of Alto Saxophone and (French) Horn in F. I had composed a soliloquy for Alto Saxophone around 3.5 years ago. I had also composed a solo for Horn in F more than 5 years ago. These "Three Sententiae for Saxophone and Horn, Op. 289" are composed in response to a call for pieces for this ensemble. I found the combination a rather challenging one to compose for. I include a title page as well as a description of the 'sententia' for those who are unfamiliar with it. The score is the transposing score, the actual pitches sounding a major sixth lower than written for the alto saxophone and a perfect fifth lower than written for the French Horn in F.
