Lesson #5. Gentle Piano: Solfeggio - Voice training. From Speech to Pitch
With the aid of the sounds of music - Do Re Mi Fa So etc - music sounds can be perceived on a stable level similar to that of human speech. The person gets used to not only hearing sounds, but also to guessing their names. The sounds that we hear are gradually decoded into their names and symbols (notes), which we can sing, play, and write down on paper.
