Piano Solo - Level 4 - Digital Download SKU: A0.954273 Composed by Adam Scott Neal. 20th Century,Contemporary,New Age. Score. 18 pages. Adam Scott Neal #2807755. Published by Adam Scott Neal (A0.954273). Program note:Tidal, for piano and fixed media, is based upon the natural harmonic series beginning on a low C (32.7 Hz). Inspired by Schenkerian analysis, I created a set of triads out of this series and ordered them based on the difference tones they create. Thus, the subtle, background tones form a large scale tonal progression, while the surface chords are sometimes seemingly unrelated. The tape part constantly moves between just intonation and equal temperament while the piano plays figurations that allude to classical sonatas. The overall form and the surface gestures expand and contract, like tidal motion and surface waves. This piece requires audio playback of a stereo file which is available on my website (www.adamscottneal.com).
