Guitoro is a free virtual guitar that lets you strum with keyboard, touch, or mouse.

Guitoro simulates strumming a real guitar in a browser, with recorded samples of four instruments: steel-string acoustic, nylon classic, electric, and four-string bass. It offers 15 chords per key, 51 songs with real parts, 56 strum/picking patterns, and 15 drum styles. Users play with keyboard (left hand chords, right hand strum), touch screen (swipe strings), or mouse. Songs slow to 20% speed, show string highlights and pick movement, and wait for chord changes. Includes tunings, capo, amp/FX, recording, and solo mode.

What commenters are saying

Commenters overwhelmingly praised Guitoro as impressive, fun, and surprisingly playable, with many spending extended time on it. Several requested features: independent string picking for fingerstyle, a left-handed view toggle (already partially addressed with Tab and Audience views), and velocity based on swipe speed. Some debated the player view orientation, with the creator explaining it matches a right-handed player's downward perspective. One commenter noted strumming feels slightly off on chord changes, suggesting shared strings should ring through. Another questioned its utility as a learning tool versus a toy.
