Stop guessing and start understanding your music
In simple terms, a musical key is like a family of notes that sound good together. When a song is "in the key of C Major," it means the note C is the "home base" or tonic, and the song primarily uses the notes from the C Major scale (C, D, E, F, G, A, B).
The key defines the mood and the harmonic framework of the music. Major keys often sound bright and happy, while minor keys sound dark or melancholic.
Most songs start and end on the tonic chord. If a song feels like it "resolves" or comes home when you play a C Major chord, there's a high chance the song is in the key of C.
In any key, certain chords are more common. For example, in C Major, you'll frequently see F Major (the IV chord) and G Major (the V chord). If you see these three together, you're likely in C.
C Major, G Major, D Major, and A Minor are the most common keys in pop.
Bb Major, Eb Major, and F Major are staples because they are easy for horn players.
Ab Major, Db Major, and Eb Major are very common for that rich, soulful sound.
