US-born musician Geoff Geer is a songwriter, composer, music theorist, performer, and educator (L2 Lead, Southwark College, 2025), with over 30 years of experience and more than 70 recordings spanning experimental, contemporary classical, electroacoustic, rock, and genre-blending work.

He holds a PhD from Oxford Brookes University (2023), with research focusing on 20th-century musique concrète and instrumental practice (viva with Howard Skempton). His work has ranked in the top 2-4% of researchers on Academia (2023-2026). He was a finalist in the UK Songwriting Contest (Fields, 2007), with 14 additional semi-final placements, and a finalist on Rollin' Good Times (Singapore TV, 1995).

His work has appeared in independent film projects, online platforms, and initiatives including Barron's Wordfest!, as well as selected radio broadcasts, including a 1993 Singapore airing of "The Real Sky".

His work bridges composition, songwriting, and production, exploring how harmonic language, texture, and studio processes shape narrative and affect. He develops hybrid works for instruments and acousmatic media, including projects for string quartet and tape.

His research advances models of instrumental-electroacoustic integration, with a focus on pitch, timbre, and perception. This includes compositional work such as iTet for Sampled Piano (1200-TET); theoretical frameworks including Logarithmic Dynamic Tonality and Ekphrastic Translation; and cognitive-phenomenological approaches such as the SIR-5 model. His work also incorporates cross-disciplinary methods, integrating linguistic syntax into compositional structure.
