A musical key
is a system of tone
s and harmonies based on a standard hierarchal
scale of seven tone
When first learning how to play any musical instrument
, it helps to know whick sharp
(s) or flat
(s) are in each key.
Here is a chart that helps one remember such, with an explanation near the bottom:
Sharp Order: F# C# G# D# A# E# B#
Major Key Sign: G D A E B F# C#
Flat Order: Bb Eb Ab Db Gb Cb Fb
Major Key Sign: F Bb Eb Ab Db Gb Cb
with "b" = flat and "#" = sharp.
How the chart works
After choosing a Major Key Sign
, that key
contains the sharp
in the line above it, and all the sharps and flats to the left
of that one.
For example, the key
of B Major
contains A#, D#, G#, C#, and F#.
of Bb Major
contains Eb and Bb.
