You are:
Chopin's Waltz #10 in B minor
Explanation:
The steps and beams refer to the musical stanza, the "path horizontally on paper". The traditional stanza has two identical parts, or "twins". Also the "three-step" refers to the music being in 3/4 time.
To figure out who I am, start by holding hands with my twin,
Start at E, but it's a tied note, ergo "holding hands"
then go up one floor and come back down.
E-F-E
Then you'll have to take a deep breath and drop down three stories - you'll be fine if you don't hit your head on the beams!
E-F-E-B, B passing into the space between the two "beams"
And finally, run back up one and come down two floors, and then go halfway down.
E-F-E-B-C-A-Ab This is the start to Chopin's waltz #10 in B minor. If you go to this online piano you can type in the notes and hear it for yourself!
