Alexander Siloti is best 
Alexander Siloti is best known for transposing one of these pieces down from E minor to B minor in his piano arrangement. A C minor piece of this kind built on quarter note chords was the basis of 22 variations by Rachmaninov. In a D minor piece of this kind, the left hand slowly continually alternates between playing D-E and E-F. The key switches between D-flat major and C-sharp minor in Chopin's op. 28, no. 15, which is one of these pieces that (*) repeats the note A-flat. Footsteps in the Snow and a piece inspired by the Ys legend, The Sunken Cathedral, are among Debussy's pieces of this type. J.S. Bach wrote a set of these pieces and fugues in every major and minor key in The Well-Tempered Clavier. For 10 points, name this type of piece that typically doesn't, as its name might suggest, serve as an introduction.
