 Born and raised in rural West Virginia Alkire utilized his skills as a guitarist and musician to become a teacher and composer for Oahu Music Company in October 1929 after having traveled to Pittsburgh to study electrical machines as an employee for a West Virginia coal company.

 In 1934 Alkire started his own company in Easton, Pennsylvania to publish music and teach the guitar.
 He utilized his knowledge of electricity to create the first 10-string electric Hawaiian guitar and his music background to create new tunings that enabled him to play four-part harmonies and rapid melodic passages that became the hallmark of his new style of performance.
Music for Electric Metronomes is an avant-garde aleatoric composition written in 1960 by Japanese composer Toshi Ichiyanagi for any number of performers between three and eight.
 The piece involves the manipulation of electric metronomes, followed by various unspecified sounds and actions.
 It is a very theatrical piece, and reflects Ichiyanagi's affiliation with Fluxus, an experimental art movement from the sixties.
 The only true scored "instrument" is an electric metronome for each individual player, though the varying sounds and/or actions may involve many different instruments and objects at the discretion of the performer.
 Because the graphic notation of score (which is a series of dashes, lines, and numbers in an erratic pattern of connected paths) leaves a lot of room for personal interpretation and expression, each performance is unique, and almost certainly cannot be reproduced.
 There is no conductor for the performance.
 It has been recorded on the album "Toshi Ichiyanagi: 1960's & 1990's".
 In a review of a performance by the S.E.M. Ensemble in 1992 at the Paula Cooper Gallery, the music critic of "The New York Times", Alex Ross, described the piece as "merely a timid, spastic prelude to György Ligeti's monumental "Poème symphonique" for 100 metronomes".
