Show HN: Guitoro, a virtual guitar you strum with your keyboard

Guitoro is a free, browser-based virtual guitar that allows users to play realistic guitar simulations using a keyboard, touchscreen, or mouse, featuring four instrument types, 51 playable songs, and 15 chords per key. The platform teaches guitar by displaying exactly which strings and techniques are used in songs, allowing users to slow down performances to 20% speed and then play along at their own pace. Every note uses real instrument recordings, requiring no download or account creation.
