App Description

Looking for something new? Bothered with primitive chords in other piano apps? No problem! This app will become a great discovery for you! By performing quartal arpeggio you will achieve your extra ordinary sounding and originality!

Quartal Harmony is a special kind of chords, which consist of intervals of the perfect fourth (P4), diminished fourth (d4), augmented fourth (A4, tritone) and sometimes doubly augmented forth (AA4, perfect quint). Such classic composers as Frederic Chopin, Franz Liszt, L. Beethoven employed similar technique. Composers who also use Quartal Harmony include A. Schoenberg, Bela Bartok, A. Skryabin, M. Mussorgsky, C. Debussy, M. Ravel, J. Sibelius, I. Stravinsky, O. Messiaen. Famous jazz musicians D. Ellington, J.R. Morton, A. Tatum, B. Evans, C. Corea, H. Hancock, McCoy Tyner, were using Quartal Harmonies in their compositions, as well as early progressive rock bands like King Crimson, Emerson, Lake & Palmer, etc.
