C Tonality

In a progression we will find the necessary information to identify accompaniment chords to the principal tonality. For example, using a progression of I – IV – V7 we can directly interpret this to certain chords depending on the tonality:



By understanding this form of noting progression, we can deduce that if the tonality of a song is in C Major, then we should use first note (hence C Major) the fourth note and fifth number (in its 7th variation).   Starting with C, the fourth note being F (C, D, E, F) and starting from C the fifth note is G (C, D, E, F, G).
