I also told you already that the notes in question usually are "arpeggios", which are the notes of a chord played in sequence, instead of all at once.
The data base from which the app chooses arpeggios is a linked bifurcated system where the computer "knows" which upper structures are consonant with which lower structures so the chords can move in leap-frog fashion: top notes can remain when lower notes change or vice versa because the moves are guaranteed to make harmonic sense.
With the glistening, rippling runs and arpeggios at which he excels, he played a chamber arrangement, accompanied by players from his Berlin Staatskapelle orchestra.
Hojun Lee's Arirang Fantasie had a hiker traversing Korea's most famous mountain peak in music perhaps a little too sweetly Westernized with consonant harmonies and twinkling piano arpeggios in a manner equivalent to Thomas Kinkade's idyllic paintings.
