Which articulation technique is described as "hammer on"?

The term "hammer on" refers to a specific technique used primarily in guitar playing. In this context, it involves pressing down a string with a finger to sound a note without plucking it again, effectively allowing for a smooth transition between notes. This technique creates a connected sound and enables faster playing phrases by allowing the player to move between notes fluidly.

Sliding from one fret to the next, while related to dynamic and expressive playing, does not describe a hammer on. Instead, it's called a slide, which involves moving a finger along the string to reach a new pitch, thereby producing a different effect. Understanding the distinction between these techniques helps in mastering different articulations and expressive styles on the guitar.
