Created especially for the Triola, it helps children continue developing their musical skills while building confidence in reading and playing music.  The colour-coded notation corresponds directly to the coloured keys of the Triola, making it easy for children to associate written notes with the correct keys. A concise introduction to rhythm further supports beginners as they progress in reading and performing music independently.  Covering the range from g' to d''', Volume 3 is an ideal continuation of the previous songbooks and a valuable resource for early music education, classroom instruction and family music-making.",
