A sharp (#) is a sign placed in front of a natural note which raises the pitch a half step (1 fret).  There is a half step between E-F and B-C naturally, so that E# sounds the same as F, and B# sounds the same as C.  For now think of these notes by there natural names only (F and C).

A sharp remains in effect for the entire measure, or until it is canceled by a
natural sign (). Once you cross into the next measure the sharp is canceled out.

Sharps, flats and natural signs that temporarily change the pitch of a note are known as accidentals.

* Note that a courtesy accidental in parenthesis is often used in the next measure after a sharp of the same letter name is used. This is not necessary but is often done to avoid confusion.

In the following exercise play the last 2 notes (G# and A) with you 4th finger. For all other notes use 1 finger per fret (1st finger=1st fret, 2nd finger=2nd fret etc...) Be sure to name the notes to yourself as you play.
