Grover* Department of Bioengineering, University of California, Riverside, 900 University Ave., Riverside, California 92521, United States * Supporting Information ABSTRACT: The frequencies of notes made by a musical instrument are determined by the physical properties of the instrument. Consequently, by measuring the frequency of a note, one can infer information about the instrument’s physical properties. In this work, we show that by modifying a musical instrument to contain a sample and analyzing the instrument’s pitch, we can make precision measurements of the physical properties of the sample. We used the mbira, a 3000-year-old African musical instrument that consists of metal tines attached to a wooden board; these tines are plucked to play musical notes. By replacing the mbira’s tines with bent steel tubing, filling the tubing with a sample, using a smartphone to record the sound while plucking the tubing, and measuring the frequency of the sound using a free
