What will happen when you use the other combinations of the keys to play?
You played a melody in major in the previous lesson, and remember you started at the key of E.
What will happen if you start at F instead?
The order of the keys is like below;
FEDE FFF_ EEE_ FAA_ FEDE FFFF EEFE D_
I believe you feel the difference between the melodies in major and minor now more than before.
Of course, expressions of the music are complicatedly connected not only by major or minor but also the pitch, tempo (speed of the music), tone, dynamics, rhythm, and many more kinds of musical elements.
You can hear the ”Mary had a little lamb" melody in the different pitch. Is this in major or minor?
