Recent simulations using finite element software have been used to study the fluid dynamics, pressure acoustics, and structural mechanics couplings involved in self-sustained reed oscillation and reed-pipe coupling in free reed instruments. This pape

In 1800, the free reed instruments of European origin did not exist. Beginning in the 1820s, there was very rapid invention and innovation in the development and production of instruments like the reed organ and accordion so that within a few decades

A khaen pipe is an open bamboo pipe of effective length L, with the free reed located at approximately L/4. The physical length of the pipe is greater than L, with two rectangular tuning slots cut into the pipe defining its effective length and resul

For free reeds in steady oscillation, the fundamental transverse beam mode dominates, but transverse modes and some torsional modes are also typically present. The motion of the free-reed tongue in early stages of the initial transient has been studi

This paper presents an overview of efforts to measure several quantities related to sound production in free reed instruments. All were undertaken with limited financial resources for equipment and a professor who started with limited experience in e

In 1990, Khosropour and Millet reported on a study of the internal spectrum of a Helmholtz resonator excited by an air jet and reported that the data for frequency and amplitude of the Helmholtz mode as a function of jet speed show a series of domain

A feature of the homophonic barbershop style is an emphasis on major and dominant seventh chords which are sung with little vibrato and with pitches adjusted to achieve tuned chords in just intonation. A principal resource for the investigation repor
