Performance Notes
1. The toms should be tuned so the four voices are easily discernible. Glomar Response was premiered using 10, 12, 14, and 16 inch toms, but other sizes are okay. If the drums have a long ring time, it can be minimized by using control rings, gel, etc.
2. The piece can be performed with the players in a shallow arc. Instead of placing the toms (and performers) very close to each other, you might want to try putting a little space (two or three feet) between them. This will help the audience see and hear the musical interactions more clearly.
3. The sound of the rim of each drum should reflect its place in the ensemble (high to low). Performers can use different sticks (different thicknesses, different woods) to help achieve the perfect variety of sounds for the piece.
