Jonathan Elkus (born August 8, 1931) is an American composer, arranger, editor, author, conductor, and teacher.
They published books and music by varying composers including Elinor Armer, Cushing, and Ali Akbar Khan.
[2][3] Elkus has focused on expanding the repertory for concert band; numerous compositions and arrangements for this ensemble have been published and recorded.
The musical style is essentially tonal, evoking the work’s period setting through galops and marches; instrumental interludes are highly programmatic, and choral ensembles make use of original onomatopoeic devices.
The music of Treasure Island is more adventurous; colorful hornpipes are used, but the language is richly chromatic and there is considerable rhythmic intensity.
