Notes: D2, A2, D3, A3, D4, A4, D5, A5
On a typical keyboard, these notes correspond to the following white and black keys:
D2: White key to the left of the "C" key
A2: Black key to the right of the "C" key
D3: White key in the middle of the keyboard
A3: Black key to the right of the "D" key
D4: White key to the left of the "E" key
A4: Black key to the right of the "E" key
D5: White key two octaves above the middle "C" key
A5: Black key to the right of the "D5" key
This pattern of D2-A2-D3-A3-D4-A4-D5-A5 can be repeated to create the intro music for the song.
