Tongan music notation
The Tuʻungafasi or Tongan music notation is a subset of the standard music notation, originally developed by the missionary James Egan Moulton in the 19th century for singing church hymns in Tonga. == The notation == Tongan music from the pre-European times was not really music in the current sense but rather a non tonic recital (like the 'pater noster'), a style still known nowadays as the tau fakaniua.
