Do you know how to sing the tonic solfa syllables of the piano chromatically. I know very well that you are familiar with d r m f s l t d. But we have more than 7 notes on a particular key. How do we call the remaining five notes.
It is pretty easy. On the key of C
In ascending order
D de r re m f fe s ze l le t d
In descending order
D t taw l ze s fe f m mo r de d
However, you can choose to use taw, mo to replace le and re respectively in the ascending order form. I hope you understand perfectly now.
