sentences:  During a sustained note, a player may use the whammy bar on the guitar to alter the tone of the note.Also, regardless of whether sustains are hit early or late, if the fret is held for the full duration of the hold, the game will always award the same amount of score increase for the note.In addition, the games support virtual implementations of "hammer-ons" and "pull-offs", guitar-playing techniques that are used to successfully play a fast series of notes by only changing the fingering on the fret buttons without having to strum each note.
