Our experience of movement and song is often enhanced when accompanied by musical instruments. This form of musical accompaniment requires a special attunement.
The musician is never the center of attention. The successful musician will play on the beat and in a spacious manner, supporting the chant, never overpowering it. It is especially important for drummers to play in a manner that makes it easier for the circle to step together.
Lead instruments may play harmonies or counter-melodies once the circle has learned the chant, but one should return and carry the melody when singers are asked to go "on the breath", that is, to continue dancing in silence for one or more verses.
All musicians need to stay constantly focused on the dance leader, who may signal subtle changes in tempo and dynamics at anytime. Musicians should not play while the dance is being taught unless asked to do so by the dance leader.
