A “slide” is executed with fretted notes on the same string and connects the sound of one note to the next. Whereas, the player picks the first note and with their finger remaining on the string, the finger “slides” up or down the fretboard to a second note without picking it - the second note then sounding. This is accomplished without taking the finger off the string or fretboard. Sliding in the direction towards the bridge raises the pitch of the note and. Sliding in the direction toward the neck lowers the pitch of the note. A slide can be the distance of one fret (fret 5 to 6) or many (fret 5 to 15)!
