Guitar technique
Hammer-ons and pull-offs (collectively called 'legato' or 'slurs') let you sound consecutive notes on one string without picking each one, using just the fretting hand.
Free for the first 3 songs.
What it is
A hammer-on adds a note by sharply pressing a higher fret onto an already-ringing string. A pull-off removes the fretting finger to expose a lower note on the same string. Together they produce smooth, fluid passages that would sound choppy if every note were picked. Legato runs are central to rock and blues soloing, fingerstyle ornamentation, and Celtic and folk styles.
How to read it
Tab notation uses 'h' between fret numbers for hammer-ons and 'p' for pull-offs. A slur arc above or below the numbers is also common. Example: 5h7p5 means pick the 5th fret, hammer-on to 7, pull-off back to 5, all on one pick stroke.
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 transcription pipeline detects legato by identifying note transitions with attack amplitudes below the picked-note threshold. When two consecutive notes on the same string share a single picking transient, the second is labeled as a hammer-on or pull-off depending on whether the pitch ascends or descends.
Where it shows up
Other techniques
The pipeline compares the attack envelope of each note. Hammer-ons and pull-offs have softer, faster attacks than picked notes. Threshold tuning is genre-aware.
Yes. Hammers and slides produce distinct pitch trajectories: hammers are stepped, slides are continuous.
