Expansion through the machine: A com-position for harmonica and wearable

In this paper, we summarize compositional processes and ideas behind the electroacoustic music work K. fn [s] + "a" (2017). The piece, written for harmonica and electronics, is directly inspired by the simplistic and minimalistic qualities of the harmonica, a compact, diatonic instrument that is idiomatically becomes part of the performer's hand and transparent on onstage. To preserve and capture these characteristics, and to extend the instrument 's sonic and performability dimensions, we utilize the Apple Watch to minimize stage presence of the "machine " while wirelessly connecting the harmonica to the computer. By maximizing onstage machine transparency, focus is redirected to the performer and music, where pure harmonica sounds, sound augmentation through signal processing techniques, and wrist-arm gestures that wirelessly shape the digitized acoustic energies breathed into the machine, are negotiated in exploring solo harmonica for the electroacoustic music medium.
