| Philip Sande wrote the etude for the workshop at the composition depeartment at the Norwegian Academy of Music. The piece was performed by matertudent Sigrun Gomnes. |
He wanted to write an expressive piece including "ping pong balls" as an ending! |
Listen to a mp3 sample from the session played by Sigrun Gomnes.  |
Scoring:
 Sande only used the 3 row of the quartertone marimba ("the quartertone flattend white keys"), and only the quartertone down symbol.
|
| "The end, drop ping pong balls on the marimba, and let them bounce freely".
