Kapustin studied piano with Avrelian Rubakh (pupil of Felix Blumenfeld who also taught Simon Barere and Vladimir Horowitz) and subsequently with Alexander Goldenweiser at the Moscow Conservatory. During the 1950s he acquired a reputation as a jazz pianist, arranger and composer. He is steeped, therefore, in both the traditions of classical virtuoso pianism and improvisational jazz.
He fuses these influences in his compositions, using jazz idioms in formal classical structures. An example of this is his Suite in the Old Style, Op. 28, written in 1977, which inhabits the sound world of jazz improvisation but is modelled on baroque suites such as the keyboard partitas composed by J. S. Bach, each movement being a stylised dance or a pair of dances in strict binary form. Other examples of this fusion are his set of 24 Preludes and Fugues, Op. 82, written in 1997, and the Op. 100 Sonatina.
Johann Sebastian Bach (1685-1750) was a German composer and musician of the Baroque period. He enriched established German styles through his skill in counterpoint, harmonic and motivic organisation, and the adaptation of rhythms, forms, and textures from abroad, particularly from Italy and France. Bach's compositions include the Brandenburg Concertos, the Goldberg Variations, the Mass in B minor, two Passions, and over three hundred cantatas of which around two hundred survive. His music is revered for its technical command, artistic beauty, and intellectual depth.
Bach's abilities as an organist were highly respected during his lifetime, although he was not widely recognised as a great composer until a revival of interest in and performances of his music in the first half of the 19th century. He is now generally regarded as one of the greatest composers of all time.
