Abstract

In the classical music world, the viola is often overshadowed by its other string colleagues, with

many preferring the pure, lively sound of the violin to that of the subdued, but richer timbre of

the viola. Apart from the viola’s larger size and lower tuning, there are a few other explanations

for this discrepancy in sound production. In a study titled ‘Acoustic Analysis of the Viola’, student

Meredith Powell recorded the viola’s open strings and compared their harmonic content to that of the

violin’s. This revealed that the viola’s mid-harmonic frequencies- in comparison to the fundamental

frequency, were relatively stronger than the violin’s. I chose to recreate this part of the project with

five violas of differing sizes for harmonic comparison. The bowed notes of the open strings of each

viola were recorded. The first eight harmonic frequencies of the notes were then plotted to reveal

each instrument’s unique harmonic signature. I found that the larger-bodied violas with warmer tones

tended to have relatively stronger low harmonics on their lowest strings. In comparison, the smaller

bodied violas with a brighter sound tended to have stronger high harmonics on their highest strings.
