As you learn to play the guitar, you will come across many questions related to how to influence the definition of your guitar chords. For example, is a C chord the same as an E . chord?. And what about the D key called?
All chords have one note which is the root or the first note of the major or minor chord in which it is played. If a chord is played in the key of E, it has the same note as the major E . chord.
If a chord is played in the key of A, it has the same note as the major chord of A. So the key of C major and the key of A minor all have the same basic note.
However, this same record can be found in two different sets of keys. The chords of C major and A minor have a different basic note than E and A.
This is because in each key, the notes used for a chord will be different. It’s easy to see that no key is the same in every key.
One thing you might be curious about is how it affects the definition in a chord if they are both in the same key. How one affects the other? It’s really hard to explain, but there’s an easy way to answer that question.
In theory, if you play a chord in a different key, the sound will be slightly different.https://inus-apcns.org/norepinephrine/ But in reality, you will only hear the difference if the chords are played in the same key.
For example, if you play a chord in the key of A, but the chord is played in the key of G, you will only hear the key of G. You will not hear the difference in the key of A. valid for B and E.
