Tonedear: Free Browser-Based Ear Training for Musicians

Tonedear is a free, browser-based ear training site aimed at musicians who want to sharpen their listening skills through repetition. It offers interactive drills for recognizing intervals, chords, scales, and melodic patterns by ear — the kind of deliberate practice traditionally done with a piano and a patient teacher, packaged into a self-serve web app that works without installation or signup friction.

Its appearance on Hacker News reflects the community’s recurring affection for small, focused, no-nonsense web tools: a single-purpose utility that does one thing well, loads fast, and respects the user’s time. For developers, it’s also a reminder that simple interactive audio applications remain an underexplored niche for the web platform.

Worth noting for readers of this publication: the source page provided almost no article text beyond its title, so this summary is limited to the site’s evident purpose. The topic is outside our usual security and infrastructure beat — it’s filed here as a culture/tools item rather than news.
