English: Piano Improvising- "Things Ain't What They Used To Be" (in educational views):

This sound file was one edition of "Things Ain't What They Used To Be" ( Mercer Ellington) with a middle improvising part travelling from American Blues Scales (In C) to c minor pentatonic scale (in E-flatten system), then getting back. It was in a smart ABA sonatina form, with an Alberti Bass (accompaniment) in the middle Andante part - B; and further, part B's peak-climbing in c-minor pentatonic scale would give us a free wandering in 'East sorrowfulness (Blues)'. This file was following another series - TAWTUTB series I had made (Educational materials for exercises: https://commons.wikimedia.org/wiki/File:TAWTUTB_with_a_solution.ogg), and for Future Learn Platform of future generations. By making it, I would like to take my first Jazz & Blue piano task and get senses of its improvising fashion in heart, meanwhile, show my respects to those people who has been working in this field bringing musical freedom to our world. Their works gave me a beautiful impression of Jazz & Blue.
