Guitar technique
Vibrato is a small, periodic variation in pitch applied to a sustained note. On guitar it's produced by rapidly bending and releasing the string in small increments.

What it is
Vibrato is one of the most personal expressive choices a guitarist makes. Two players can play the same note with very different vibrato width (how far above and below the resting pitch the note travels) and speed. Wide, slow vibrato is associated with blues and classic rock; tight, fast vibrato is common in shred and metal. Some players add vibrato to almost every sustained note; others use it sparingly for emphasis.
How to read it
Tab notation shows vibrato with a wavy line (~~~) above the fret number for the duration of the vibrato. Some systems mark width as 'wide vib.' or with a labeled bracket.
See the full guide to reading guitar tab for the complete symbol reference, or browse the glossary for related terminology.
How audio2guitar detects it
The pipeline detects vibrato by analyzing periodic pitch oscillation around a sustained fundamental. Vibrato is marked when the oscillation amplitude and frequency fall within the typical guitar range (roughly 5-10 Hz oscillation, ±20-50 cents).
Where it shows up
Vibrato is marked as present or absent on each sustained note. Width and speed annotation is a future improvement; the wavy-line notation in the rendered tab follows standard convention.
Whammy bar vibrato produces the same pitch oscillation pattern at the audio level and is detected the same way; the tab notation does not currently distinguish bar from finger vibrato.
Every vibrato our pipeline detects gets marked in the tab automatically. First 3 songs free.
