A song on
guitar that has a non-
standard tuning.
Standard tuning on a guitar is
EADGBE. A song which does not follow this tuning is generally said to have an altered tuning. Some altered tunings include:
"
The Rain Song" by
Led Zeppelin --
DACGCD
"
She Talks to Angels" by
The Black Crowes --
EBEG#BE
"
Fearless" by
Pink Floyd
It is important to note that generally a song which is in a
drop d tuning or is tuned down 1/2 step is generally not considered an altered tuning. Partialy because these songs do not change the
chord structure significantly.
