Music theory Q
I’m making some progress in theory, around the Circle of 4ths/5ths,
intervals and triads. My little niggly doubt is my understanding of key
signatures; so…….. if I play a standard F-major barre chord I am
playing in the key of C, because the notes are F, C and A, and the only
major key signature with an unsharped-F is C. But when I play an open
D-chord I am in the key of D because we have A, F# and D, and D is the
root note. Am I on the right lines here? Cheers. -

The chord of D Major (D, F#, A) is the 1-chord in the key of D-Major. However it’s also the 4-chord in the key of A-Major, and it’s the 5-chord in the key of G-Major.
1-4-5
G Major G-C-D
D Major D-G-A
A Major A-D-E
Hoping that helps with your question? And hope you are enjoying your music theory studies 🙂

Hello Carol, thanks for your answer. I sort of understand; I think I need to get into intervals a bit deeper to make sense of it. I’m ok with the concept of major and minor 3rds and the 1 3 5 chords Major, Minor, Diminished and Augmented. Yes I’m loving it! I’ve got a mathematics background and I’m finding music theory to be beautifully precise, everything connects. Thanks again.
