Year 9 Tonic-Dominant relationships

Here is a picture of the basic information we went through today.  Key things to remember:

1) The Music Department is like the home key (tonic). 

2) Ms Doan could be compared to chord I and Mr Guinane as chord V (tonic-dominant relationship)

The most important thing to remember is that the tonic and dominant are the linchpins of the rest of your life, civilisation and humanity.
