He was the son of Franz Theodor Schubert, a schoolmaster and Elisabeth (Vietz). His musical genius, as singer, musician, conductor and composer, was recognished at an early age.
One of the greatest composers of the late Classical and early Romantic eras, Schubert's music was very popular and much performed, particularly in the early 19th century. Among the most popular were the 'Moments Musicaux', D780 (Opus. 94).
The first bars of Schubert's third 'Moments Musicaux', were transcribed by Whistler on a sheet of music that appears in his grotesque caricature of F.R. Leyland, The Gold Scab y208, painted in 1879. The third of six movements, 'Allegro moderato in F minor' (which ends in F major) was - and is - much performed.
