Resolve: Reactive Ear Training
Connect what you hear & play
$24.99 · Designed for iPad. Not verified for macOS.
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.
