An expert on classical guitar technique and repertoire, as well as jazz improvisation, Cosley has successfully prepared students to attend top institutions such as the Berklee College of Music.
Three intensive years as teaching assistant to renowned pedagogue Ricardo Iznaola strongly influenced Dan’s teaching and learning approach.
For three years he served as professor of music at Marylhurst University in Portland, Oregon, where he taught classical and jazz guitar, orchestration, guitar ensemble, notation, and composition. He also founded the university’s improvisation festival, organizing a concert and free-improvisation masterclass with guitarist Marc Ribot.
While living in Portland, he also served as conductor of the Portland Community College Chamber Ensemble, and was also a member of the guitar, composition, and theory faculty.
In 2017, following the closure of Marylhurst University, Cosley took leave from academia and relocated to Kyoto, Japan, to intensify his composition and performance activities and establish wayoftheguitar.com, a comprehensive online training system for fret-board harmony, aural skills, and improvisation.
Cosley received a dual Master’s degree in classical guitar performance and composition from the Lamont School at the University of Denver where he studied classical guitar performance with Ricardo Iznaola and Jonathan Leathwood, and composition with Samuel Adler.
While at Lamont, Cosley became the first guitarist in the conservatory’s history to win first prize in the school’s concerto competition, as well as the first student to début an original concerto on a graduate recital. He was recipient of the Ricardo Iznaola Scholarship, and the Graduate Recital of Distinction award, among many of the school’s other top honors.
Cosley is fortunate to have been mentored by a number of leading musicians including saxophonist Roscoe Mitchell (Art Ensemble of Chicago), guitarists Leo Kottke, Marc Ribot and Roland Dyens, and multi-instrumentalist Ian Underwood (Frank Zappa).
Cosley’s recordings span several genres including classical (Bach, Villa-Lobos), jazz (Mingus, Ellington), prog & math rock, and free-improvisation.
Notable collaborations include duos with guitarist-composer Nathan Kolosko, session work for producer Michael Hoppé, head of A&R for PolyGram Records (Vangelis, The Who, ABBA), and cinematographer/trumpeter Christopher Fryman.
Cosley has published original work with Canadian publisher Les Productions d’OZ, and independently.
The Guitar Ensemble Association of Japan commissioned the substantial Waltz Triptych for guitar quartet, a work that has had multiple performances in Japan since its première in 2010.
Other works include various pieces for solo guitar, guitar ensemble, and various chamber ensembles.
Cosley premièred his Concerto for Guitar in Denver, Colorado, in 2005.
Multiple jazz & free-improvisational works have followed, including many rock-influenced works for electric guitar, bass, and drums.
Cosley has published arrangements of diverse composers such as Bartók, Beethoven, Ellington, and Monteverdi, with Canadian publisher Les Productions d’OZ, and Japanese publisher Gendai Guitar.
His ground-breaking solo electric guitar arrangements of the music of Charles Mingus have been met with considerable acclaim.
In 2016, Oregon Koto Kai, one of America’s top Japanese music ensembles, commissioned Deep River, a trio for two 13-string kotos and 21-string bass koto. The ensemble premièred the piece at Portland State University during their 5th Anniversary Gala concert.
For two years, he served as staff engraver and editor of masses, motets, and Gregorian chant for the world’s largest Catholic publisher, Oregon Catholic Press.
A seasoned performer, Cosley has premièred works by the world’s leading classical guitar composers, including Roland Dyens, Stephen Goss, Atanas Ourkouzounov, and Gilbert Biberian.
He made his European debut at the Rome Festival (Italy) in 2000, at the age of 21, performing the music of Heitor Villa-Lobos and Joaquín Turina.
Other notable performances include appearances at the Up-Close Avant series (Denver, Colorado), and the Shonai International Guitar Festival (Japan).
In 2013, the legendary luthier Robert Ruck selected Dan to demonstrate two new instruments in a solo concert at Marylhurst University.
He has performed with many artists outside of the classical domain, including Norihiko Hibino, Samm Bennett, Mike Rivett, and Chris Broderick.
