He also serves on the music faculty at Loras College as an adjunct professor. Alongside his administrative and academic roles, he continues to compose, record, teach, and perform, pursuing a lifelong investigation of the guitar’s expressive range.
Long Bio
Dan Cosley is an American guitarist, composer, and author whose work moves fluidly among classical tradition, jazz improvisation, and experimental music. Known for his inventive musical voice, improvisational fluency, and distinctive contributions to contemporary music, Cosley is recognized for a rare combination of interpretive, compositional, and improvisational abilities. He was a protégé of the renowned guitarist-composers Ricardo Iznaola and Roland Dyens.
Born in Dubuque, Iowa, in 1979, Cosley was shaped early by the musical currents of Chicago, whose creative traditions became an important part of his artistic outlook. He studied early with the Emmy Award-winning guitarist and composer Jaime Guiscafré, who introduced him to the classical guitar, particularly the Cuban and South American repertoire. Through Guiscafré, he met and was deeply influenced by Roscoe Mitchell, the saxophonist, composer, and founding member of both the Association for the Advancement of Creative Musicians and the Art Ensemble of Chicago.
At the invitation of the Rome Festival, Cosley made his European debut in 2000, performing music by Heitor Villa-Lobos and Joaquín Turina. In 2005, he received a dual master’s degree in classical guitar performance and composition from the Lamont School of Music at the University of Denver. During three years of graduate study, he worked closely with Ricardo Iznaola and served as his graduate teaching assistant. He also studied technique, repertoire, and chamber music with Jonathan Leathwood and Masakazu Ito, and composition and orchestration with the visiting professor Samuel Adler, a longtime composition professor at the Juilliard School.
At Lamont, Cosley became the first guitarist to win the school’s Concerto Competition, performing the Villa-Lobos Guitar Concerto, and the first student to premiere an original concerto as part of a degree recital. While in Denver, he also premiered works by Stephen Goss and Gilbert Biberian under the guidance of Jonathan Leathwood. He was the second recipient, after Leathwood, of the Ricardo Iznaola Scholarship and received the Graduate Recital of Distinction award.
After completing his graduate studies, Cosley relocated to Tokyo, where he joined the Tokyo Guitar Ensemble. He appeared at numerous festivals and concert series throughout Japan, premiering works written for the ensemble by such prominent guitar composers as Roland Dyens, Benjamin Verdery, and Atanas Ourkouzounov.
Cosley also became a fixture on Tokyo’s improvisational scene, collaborating with Samm Bennett, Norihiko Hibino, and Mike Rivett. He performed frequently at some of the city’s leading music venues, including SuperDeluxe and Nakano ZERO.
In 2010, Cosley became the third non-Japanese composer, after Andrew York and Roland Dyens, to receive the prestigious commission for the Japan Guitar Ensemble Association’s annual gala concert. The resulting work, Waltz Triptych, is published by Les Productions d’OZ. He was later elected the association’s first non-Japanese director, a role that included writing articles, arranging music, overseeing numerous publications and recordings for Gendai Guitar, adjudicating competitions throughout Japan, and appearing at festivals including the Shonai International Guitar Festival.
After the 2011 earthquake in Japan, Cosley relocated to Portland, Oregon, where he initially worked for Oregon Catholic Press as a staff engraver and editor of masses, motets, and Gregorian chant. From 2012 to 2016, he served as Professor of Music and Director of Guitar Studies at Marylhurst University. He also taught at Portland Community College and served on the board of directors for Classical Revolution PDX.
In Portland, Cosley designed and taught numerous university courses, including applied classical and jazz guitar, music theory, orchestration, notation, music technology, music history, and composition, and directed several ensembles. In 2013, the legendary luthier Robert Ruck requested that he demonstrate two new instruments in a solo concert devoted to the music of J. S. Bach and Francesco Canova da Milano.
Cosley has long maintained a deep interest in traditional Japanese music, particularly the koto music of Tadao Sawai. In 2016, Oregon Koto-Kai commissioned Deep River, a trio for two 13-string kotos and 21-string bass koto. The work premiered at Portland State University during the ensemble’s fifth-anniversary gala concert.
During his Portland years, Cosley was mentored by the multi-instrumentalist Ian Underwood, whose credits include Frank Zappa, Quincy Jones, and James Horner. He organized a free-improvisation concert and masterclass series featuring guitarist Marc Ribot and performed on sessions for producer Michael Hoppé, the former head of A&R at PolyGram Records, whose roster included Vangelis, The Who, and ABBA.
From 2017 to 2022, Cosley lived in Kyoto, Japan, where his work centered on composition, improvisation, recording, and the development of his online teaching platform, wayoftheguitar.com. While in Kyoto, he co-founded Cosmic Fugue, an improvisation concert and workshop series, with the trumpeter and cinematographer Christopher Fryman, known for his work on Carl Sagan’s Cosmos. He performed extensively with musicians, including Dave Moss, associated with Ornette Coleman, and Yasutaka Okada of kott.
In Kyoto, Cosley was an active performer at leading venues, including UrBANGUILD and Live Spot RAG, regularly collaborating with leading musicians and butoh dancers. He also scored films and television episodes for Japanese studios, including TOEI, working with directors such as Minami Goto and Ryoma Masumoto.
In addition to his substantial output as a recording artist, Cosley has authored more than 40 published titles, including original compositions and arrangements with the Canadian publisher Les Productions d’OZ and the Japanese publisher Gendai Guitar, as well as self-published textbooks on music theory and improvisation. His published arrangements include works by Beethoven, Ellington, and Monteverdi, and his solo electric guitar arrangements of Charles Mingus’s music have attracted considerable acclaim.
In 2022, Cosley studied constraint-based and algorithmic composition at Stanford University’s Center for Computer Research in Music and Acoustics. His interest in computer-assisted composition led to the publication of The Art of Canon: 254 Two-Part Inventions, a 15-volume series of Renaissance-influenced, two-voice modal counterpoint for flexible instrumentation.
Cosley relocated to Seattle in 2022, continuing his wide-ranging work as a performer, improviser, composer, recording artist, and educator while teaching at Edmonds College. He performed and recorded with leading figures in the city’s creative music scene, including the trombonist and conductor Christian Pincock of Scrambler and the drummer and composer Matt Jorgensen of Origin Records. In Seattle, Cosley performed as a member of the Scrambler ensemble and formed the band Known Senders with the bassist Sam Hallam.
After returning to his hometown of Dubuque, Iowa, Cosley became a director at Northeast Iowa Community College, where he oversees programs across the college’s eight-county district. He also serves on the music faculty at Loras College as an adjunct professor, continuing his long-standing work as an educator. From Dubuque, he continues to compose, record, teach, and perform work that bridges classical tradition, jazz improvisation, and experimental sound.
