If it is desirable to change the key of a song because, for example, it doesn't match the voice range of the singer, it can be transposed to a different key.  Or, the key can be effectively changed by using a capo and then playing the same notes and chord patterns in the new position on the instrument neck.

To change the key of a song that is in the key shown in the left (brown) column, place a capo on one of the fret numbers shown. The new key is shown at the intersection of the capo column and the original key row.

Note that while a capo always raises the pitch of the instrument, it can actually lower the pitch of the voice if the singer shifts down to the next lower octave.

On most guitars, it is difficult to capo much beyond the seventh fret, so those cases are shown in red in the table.
