I’ve noticed that some music is written in C major, others in A♯/B♭ major, D major, E major, etc. What factors influence an artist’s or composer’s choice of key?

Even watching videos of known producers, they change a key from song to song.

let’s stick to electronic instrumental music, to avoid a singer vocal range issues.

with regards

I often hear ideas in my head first. So the key gets decided at that point, mostly. At other times, I’m just improvising at the piano. Something will catch my ear… and there’s the key.

The key initially becomes whatever pops out of my head, though sometimes I'll change it to accommodate my voice, though I've recently given up singing due to having a small range and having better synthetic alternatives.

Oh, I should also comment that a lot of the time the key is dictated by the fact that I'll sometimes write for guitar.

Actually there's 3 things (saying this as an ex music student):
1. payability/singeability - any idea should be memorable enough to hook you. And it's simply easier to create a hooky melody if you can also sing it.
2. Challenge creates inspiration, which means to play in a an unfakiar key c<n bring back that sensation of rediscovering music aon a new level again and not being stuck in a habbit.
3. The idea in your head ddemands that key.
4. You simply took the chords of your favourite song as a basis and never changed the key

You pick the key based on the weakest link in your band, usually the singer

I think key is not really that important, but diatonic chords (those derived from a corresponding scale) can provide a good guide for chord selection.

I think key has much more to do with music notation. You can limit how many accidentals (sharps and flats) within sheet music, by picking the key that most reflects the notes in your melodies and chords.
Similarly, orchestral and band instruments are transposed for a similar reason. Transposition keeps the notes centered on the notation staff.
(I.e. Bb Tenor sax)

Picking the correct key
