he theremin is one of the first elec- tronic musical instruments and one of the few played without physical contact since it only re- quires hand and finger movements to control the amplitude and frequency of the musical note. However, the capacitive functioning of the anten- nas increases the sensitivity to electrical interfer- ence, its timbre is fixed, and the frequency an- tenna's vertical arrangement could limit the use of people with amputated fingers. Furthermore, it does not contain any help to guide the execu- tion, which makes it a very difficult instrument to play. In this paper, we present the development of a digital optical theremin with an audio syn- thesis process, intuitive graphical interface, frequency antenna in the horizontal position, and linearization of the frequency-distance relationship. These features are intended to aid learn- ing and interpretation of the instrument and ex- tend access to people with finger limitations. In order to validate the instrument's behavior and characteristics, we conducted three experiments: 1) accuracy analysis of the linearization through the mean absolute error in units of cents and the Kruskal-Wallis statistical inference test, 2) val- idation of the steps of the audio synthesis mod- ule, and 3) checking of the timbral diversity, both through the Fourier spectrum. This prototype could be used as an auxiliary tool in musical initi- ation and the development of musical perception.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
