A key signature in music means the set of flats and sharps that are based on any root note. Keys have a big impact on the tone and mood of musical piece. An understanding of music keys is essential, particularly when you wish to jam with other artists. It can be tough to find a key, particularly if you lack prior music training. Here are some ways to know which key you are playing.
Find the tonic note
In a key signature, the tonic is the root note on which the remainder of the scale is based. Tonic is vital given that any specified set of flats and sharps could match either a Minor or a Major Key. If the remainder of the composition seems to be created on a chord, the root note of the chord is likely to be the tonic note.
Identify the chords being used
There are chords that are appropriate for musical keys. Check the notation to spot the chords being used. You can then use a chord map for relating the chords with a music key. Chord maps are the thesaurus of all the chords applying to any specific key. If you can spot 3 – 4 chords at least, you can get sufficient data to detect the key with the aid of a chord map. Chord maps clearly outline every key chord. For instance, in the C key, the chords are:
- A Minor
- C Major
- D Minor
- E Minor
- F Major
- G Major
Use the Circle of Fifths for reference
The Circle of Fifths happens to be an easy way to remember the flats and sharps in a specific Major Key. It is, in a lot of ways, the most vital tool in the world of Western Music. Count how many spaces are there clockwise from C between a note, if you want to know the number of sharps in a key. C is located in the Circle of Fifths at the top, which makes it easily countable. Count the number of sharps in a clockwise fashion. The Major key will be the spot where you stop at.
Detect the song’s final note
A song’s final note, in many cases, can bring back the composition to the root tonic note. A lot of music composers use a tonic note to end with, in order to give a sense of finality to their work. Use the give flats and sharps for cross-reference of your final note.
