The Exposition
We combined metal and found objects to make swinging pendulums. These pendulums sway freely and pluck piano strings as they move. At first, the person swinging them controls the sound, but eventually, gravity takes over, creating natural, unplanned melodies. It’s a collaboration between human control and the forces of nature, resulting in beautiful, spontaneous music.
The Dénouement: Final Instrument Image and Video Gallery
The video below shows our final work displayed in the theater space in Ottumwa. The images are of the final piece as soon as we finished assembling the instrument. The simple black metal worked well in the space with the lights shining over it from the balcony. It created intriguing and unique shadow effects across the area in the theater, making the instrument feel more imposing on the space than it was. During our photoshoot for the images below, we focused on getting the compelling angles of our project. Our favorite photos are those of the picks and weights while in motion.
ACT 1: Sketching, Ideation, & Collection
Our project initially aimed to generate sound with swinging string pendulums. Space limitations prompted a shift in strategy towards crafting frames for the pendulums to facilitate direct string plucking. This adaptation enhanced playability and control. The process involved meticulous material selection and frame design. We explored various options, ensuring each element contributed to both functionality and aesthetics. Prototyping and refinement were crucial, providing the instrument’s seamless integration.
ACT 2: Early Prototypes
Our initial prototypes revolved around fine-tuning connections and mechanisms. Transitioning to larger wooden prototypes, sound production became more intuitive. Our group created two wooden prototypes. The first was to prove our concept with one string and one pendulum, and another to identify challenges when adding more complex mechanisms. Additionally, we seized the opportunity to acquire certifications for metalwork, essential for welding components. The pivotal focus in our final prototypes was the structural integrity, particularly the frame bracing and the horizontal bar’s load-bearing capacity. These trials enabled us to preempt challenges in the metal installation phase, streamlining the overall process.
ACT 3: Production Process
We learned many new skills in the production of this instrument. Welding and other metalwork were our most significant obstacles to overcome, but once we got over the learning curve, things came together nicely. The frame is all welded together and ground down to look cleaner. We ended up salvaging pieces from an old piano for the tuning pegs and hitch pins, as well as some brake rotor drums for the pendulum weights. Our instrument has a very industrial look, which gave us an excellent opportunity to salvage and reuse as many pieces as possible.
