Resolve is a powerful ear training system, developed by Tom Quayle and David Beebee, combining a structured video course with a custom practice tool. The course and practice tool are designed to work together: the videos explain the concepts and exercises, while the practice tool generates the harmonic material you use to train your ear on your instrument. Reactive Ear Training focuses on developing a direct connection between your ear, your fingers, and your instrument. Resolve generates random, non-functional chord voicings for you to react to by playing over each chord using the exercises taught in the inlcuded course. The Harmonic Complexity Slider lets you tailor the sounds to your ability, from simpler, more consonant voicings at lower settings to increasingly complex and dissonant sounds at higher settings. Practicing this way strengthens the connection between your ear, your fingers, and your instrument. Over time, this develops stronger musical instincts and a deeper, intuitive understanding of harmony that maps directly to your instrument and translates to real musical situations.

You'll want to have 3-4 GB available to download them fully and allow them to decompress properly. If you're still having problems please contact support at feedback@solotrainerapp.com ### 5/5 — Addictive Ear Opener *2026-05-16* Just downloaded the app, watched the introduction videos and started: appealing user interface, easy to use, beautiful sounds. And I could play along. Wonderful experience. Thanks a lot. Highly recommended. ### 4/5 — Will Be Amazing w/ a Few More Settings *2026-05-16* Whether you’re trying to do as the app is intended for and practice playing over chords on reaction, or you just want to practice some exotic scales over appropriate chords, this app is an easy to use, fantastic practice tool. I’d give it 5/5 with just a few strangely missing features: the gap of time between chords is far too long, and there should absolutely be a setting to adjust this. You can already control how long a chord is played for, but not how long the space is before the next chord breaks the silence. Additionally, 5 seconds is still a really long time to wait if you’re a more advanced player and you’d like to practice over fast, practical changes. I’d love to see an update that allows fast, gapless chord changes, perhaps with some simple drum loops as an option as well. Basically an endless, random backing track. Overall loving this app and hope to see more features added! ## Frequently asked questions about Resolve ### What is Resolve's primary function?
