Music education software developer, Joerg Garbers today is thrilled to announce the release of Guidonian Hand 1.0 for iPhone, iPad and iPod touch. In Medieval music, the Guidonian hand was a mnemonic device used to assist singers in learning to sight-sing. With the app users can learn how it was used and have some fun making music.
This app turns images of the Guidonian hand into a keyboard which users can play. Users can also play on photos of real hands thanks to hand recognition. Each joint and tip of a finger is a key which plays an instrument tone, a SolFa solmization syllable or a MIDI pitch.
Guido of Arezzo or Guido d’Arezzo (c. 991-992 – after 1033) was an Italian music theorist and pedagogue of High medieval music. Guido developed new techniques for teaching, such as staff notation and the use of the “ut-re-mi-fa-sol-la” (do-re-mi-fa-so-la) mnemonic (solmization).
In teaching, an instructor would indicate a series of notes by pointing to them on their hand, and the students would sing them. The notes of the gamut were mentally superimposed onto the joints and tips of the fingers of the left hand.
