The Library of Musical Overtone Sounds for Piano is a collection of 88 acoustic piano tones recorded on a 7 foot Kawai grand piano.
In order to create an experience of natural acoustic sound, each tone has been professionally recorded to capture a maximum amount of overtone resonance. Acoustic tones have been chosen because they generate spectral ratios of the harmonic series and create a higher capacity for the auditory system to detect change (Golumbic, 2007.)
The collection is organized by note name so that custom protocols can be designed and preferences can be chosen from a menu. For instance, the note A has options for: a) short tones; b) long resonant tones; c) notes in different octaves; d) notes in overtone ratios of the fundamental; e) intervals and chords; and f) tone sequences (e.g., overtone series and circle of fifths.)
The Library comes with a musical intake and user manual.
