Welcome! This website is designed to keep everyone up-to-date with my latest projects. I’m currently an Assitant Professor of Music at Eastern Mennonite University. My research interests include music technology, creativity, and artificial intelligence. Feel free to explore past projects I’ve worked on.

Astral Recording Studio
I recently helped build a state-of-the-art Dolby Atmos recording studio at EMU as we build our music technology program. Our studio features:
🎙 Isolation Rooms — Acoustically treated spaces for crystal-clear sound, from intimate solo sessions to full band recordings.
🎧 Dolby Atmos Control Room — Industry-standard digital and analog equipment for immersive mixing and mastering.
🖥 Editing Suite — Dedicated space for precise audio editing, sound design, and finishing touches.
🎸 Instrument & Equipment Library — From premium microphones to sample libraries and plug-ins, everything you need to produce your best work.
Harmonic Composer is a music theory and composition tool for creating, visualizing, and hearing chord progressions in real-time.
- Build chord progressions with an intuitive drag-and-drop timeline
- View proper voice leading in grand staff notation (SATB four-part harmony)
- Hear your progressions with MIDI playback
- Explore chord inversions, extensions (7ths, 9ths, etc.), suspensions, and tensions
- Access common chord progressions to jumpstart your compositions
- Experiment with multiple voicing arrangements for each chord
- Work with advanced harmonic concepts like secondary dominants (V/V, vii°7/V)
- See proper musical notation with courtesy accidentals and correct enharmonic spelling
Perfect for:
- Music theory students learning harmony, voice leading, and chord progressions
- Composers and songwriters experimenting with harmonic ideas
- Music teachers demonstrating voice leading principles and harmonic concepts
- Arrangers working out SATB vocal or instrumental arrangements
- Self-taught musicians exploring how chords connect and resolve
The app bridges the gap between theory and practice by letting you instantly see and hear how your harmonic choices work in proper four-part voice leading.
