The instructions for the third and fourth studies in this project are to create percussion duets with less familiar time signatures – 5 and 7 beats to the bar respectively. I have made notes on my research into this area in my learning log here.
In this first example in 5/4 time, I decided on a regular pattern to the beat groupings: a bar of 3+2 followed by two bars of 2+3. As I noted from my reflection on Boris Blacher’s music, my ear tends to be drawn to patterns that can be easily distinguished. I tried to achieve this here by emphasising the grouping arrangement from the start with a grace note on the castanets in the appropriate place, and reinforcing it with the sparse accompanying line on the Iya drum playing on the same beats. I also decided to use dynamics to further highlight the pattern (louder in the first bar of each repetition of the pattern).
A note on the instruments: the Iya is a type of Bata drum, a cylindrical shaped instrument traditionally played in Cuba and made from leather. At the end of the piece I made this instrument the focus of the music and experimented with some rapid changes in dynamics.
My second study is in 7/4 time, and this time I experimented with a closer relationship between the two instruments (i.e. the individual lines only make sense when played together), which I found harder to achieve to my satisfaction. Every second bar is a repeat of the previous bar with the two instruments swapped over, as they though are doing a dance with each other.
