Rocket Blastoff - Tetris (GB)
Rocket Blastoff plays after Type-B's Level 9 Height 5 has been cleared. After the cutscene of the Russian dancers with Trepak playing in the background, an additional cutscene is shown of a rocket launching off of a launchpad. After this, the text CONGRATULATIONS! is displayed on screen.
The song is in the key of A♭ minor. The second square wave plays the following notes, all 8th notes, with the first square wave echoing the second square wave:
A♭ C E♭ A♭ B♭ D♭ F B♭ C E♭ A♭ C D♭ F A♭ D♭ B♭ D♭ F B♭ G B♭ D♭ G
The bass holds an A♭ for a dotted half-note, then plays an octave lower A♭ quarter note, and then loops.
The chord progression is as follows:
A♭ B♭m/A♭ A♭ D♭/A♭ B♭m/A♭ G°/A♭
