Product details

Transposed Dekany was written to be played by a large consort of musicians using a collaborative iPhone app called the satellite gamelan. Written by the composer in the Objective C language, this app makes the iPhone a performing instrument that is easy to play and quick to learn. Played as a consort, the instruments introduce both new players and seasoned instrumentalists alike to the world of microtonal music.

Transposed Dekany is composed in a 10-note microtonal scale created from five harmonics using a method devised by contemporary tuning theorist and instrument designer Erv Wilson. The scale is in fact two interleaved pentatonic scales which are harmonically remote from each other. Many additional pitches are heard as notes in the scale are transposed. Different parts of the work play different transpositions of the scale resulting in the creation of new timbres.

Sounds used in the work are mobile variants of software instruments devised by Jean-Claude Risset, the composer who pioneered creation of the first software instruments at Bell Labs in 1968. One sound used in the app is Risset's chorus instrument, the other is Risset's bell instrument. Variants of both sounds depend on selections made by players during performance.
