How to Tell the Key of a Piano Song
Every piece of music is written in one key or another, such as the key of Bb or the key of E or whatever. The key signature at the beginning of a score tells what sharps or flats are being used in the song, and therefore what scale the song is based on.
There is a key signature in all pieces of music. It is signified just after the clef (the staff) and includes symbols for flats (b) and sharps (#). When you take a careful look at the start of each of the lines in the music you will surely recognize a grouping of flats or sharps (never both at once). They appear either on a space or on a line of the music staff and are put there to signify the notes that will be affected by them. To say it a different way, if the #, or sharp, is placed on the top of a music staff, the F note will be played as F#. This means that anytime the note F is played, no matter if it is in the staff’s first space, on top of the staff, or below or above the staff (this will be signified by the ledger lines) it will be played as F#.
If a note that is dictated as sharp or flat by the key signature is to be played as natural, an accidental is placed before the note. For example, if an F (natural) is to be played in the key of G, an accidental has to be placed before it so it is not played as an F#.
The key signature is used so that the number of sharps or flats that are used in within the music itself will be limited. With this said, the musician can tell from the start that each time the note F is played it is to be played as a #. There is no need to put the # in front of each and every F note in the sheet of music. If the signatures were not used, the music would be very hard to decipher because there would be flats and sharps scattered throughout the music, causing cluttering on the lines of music.
The most common key signatures are listed below along with the notes that are affected by them:
Key of C: No flats or sharps
Key of G: One designated sharp (F#)
Key of D: Two designated sharps (C# and F#)
Key of A: Three designated sharps (C#, G# and F#)
Key of E: Four designated sharps (D#, F#, C# and G#)
Key of F: One designated flat (Bb)
Key of Bb: Two designated flats (Eb and Bb)
Key of Eb: Three designated flats (Ab, Bb, and Eb)
Each key also has it’s own relative minor. Though a major and its relative minor are similar in almost every way (their scales are the same though started in different places), they are thought of separately. A relative minor is named by the note that is a minor third down from the major (key). Another way to think of it is the relative minor is named by the sixth note in the major scale. For example, the note A is the six note of a C major scale, so an A minor is the relative minor to C. The use of a particular key’s relative minor is very common in music and knowing them goes a long way in understanding a song’s chord progression.
Here are some keys and their relative minors (keys).
A minor is the relative minor C
B minor is the relative minor for D
F# minor is the relative minor for A
G minor is the relative minor for Bb
When a musician is experienced and plays his music in a nontraditional setting, like when they play free style with not music to read, all he really needs to know is the key that the music was written in and he will be able to play the scales or melodies and the necessary chords that will allow them to play the song freestyle.
Lastly, a song being written in more keys than one is fairly common and the key changes in the middle somewhere. The newer musicians may have difficulties when the keys change like this.
