C.P.E. Bach: Solfeggietto (synthesized)

YouTube Uploaded by ScrollingMusic on May 12, 2011

"From WP:

Solfeggietto (H 220, Wq. 117: 2) is a short solo keyboard piece in C minor composed by C. P. E. Bach. Played at a tempo of Allegretto (Or Presto to Pretissimo, by some), it requires well-trained, dexterous fingers and much practice to be played well and at a consistent pace. The piece is not meant to be played at a fast, rushed pace, but more an even, quick pace. It contains changing C minor arpeggios and fast 16th notes. Some pianists use Solfeggietto to warm up their fingers for a performance.

This synthesized rendition was generated from a MIDI file by our Matlab synthesizer. For this piece, we used our "amvoice" instrument. Instead of generating a unique timbre through additive synthesis, like most of our instruments do, it generates sound through amplitude-modulation (AM) synthesis, multiplying fundamental sine waves instead of adding them. This allows a harmonic-rich tone to be created in a very efficient manner, with a run-time much faster than additive synthesis instruments of a comparable tone quality."

Matlab Synthesizer - Beethoven: "Waldstein" Sonata

"Ludwig van Beethoven (1770-1827): Piano Sonata No. 21 in C major, Op. 53. I. Allegro con brio

This sonata is considered to be one of Beethoven's greatest and most recognized, and one of the three particularly notable ones of his middle period. Beethoven completed this sonata, one of his most technically challenging works, in the summer of 1804. During this time, Beethoven had begun to develop hearing problems that would lead to his deafness in later life. The "Waldstein" name comes from the sonata's dedication, to Count Ferdinand Ernst Gabriel von Waldstein of Vienna, a close personal friend of Beethoven's.

This synthesized rendition was generated by our Matlab synthesizer. For this piece, we programmed a very velocity-sensitive sound whose harmonics change with changing dynamic levels. Volume levels alone are not enough to convey the vast scope and grandiosity of this work. The colors in the scrolling visualization correspond to dynamic levels as well, with red being the loudest notes in the piece."
