This is a musical scale training for C Major, C Minor and C#Minor scales.
Follow Katie, the host for its instruction. Click to choose your musical instrument and then click to select the scale. Now, you may sit and watch the presentation.
Thanks to edX and its HarveyMuddX: CS002x Programming in Scratch course that gave me the idea to play musical scales.
This is to combine the skills learned to draw, and play sound into a mini project.
