Beating tones inspired a work for marimba and percussion.
Performed by percussionists Rebecca Celebuski and Peter Scholes at Auckland Chamber Orchestra's Composer Portrait concert dedicated to the music of Annea Lockwood.
Annea Lockwood writes:
“I love the effect of two tones very close in pitch beating together. When the American percussionists Dominic Donato and Frank Cassara asked me to write them a piece for marimba, in exploring the instrument, I was struck by the waves of beating tones which can be drawn from the resonators in the low register. We then found that the quartz bowl gong’s purity of tone also created strong beats when a semitone away from pitches in the mid register. So Immersion explores these possibilities, intercut with the tam-tam’s more acidic sounds.”
She wrote Immersion in 1998.
