The Hammer-on
A hammer-on is a technique where the first note is picked but the second note sound is produced by "hammering" the left hand finger onto the fretboard. The hammer-on is indicated on the music staff by a curved line joining two different notes. In Tab notation the hammer-on is indicated by a curved line and the letter H above it.
The hammer-on is performed by playing the first note (in the following example - a C note on the first fret of the second string) with the m finger. While this note is still sounding, the third finger of the left hand hammers down onto the second note (a D note on the third fret of the second string). The second note is not picked; the sound is produced entirely by the left hand "hammering" onto the string as shown in the photos.
Starting position – C note
