I was wondering if chord progressions and melody have to sound a certain way to be part of a style of music? Like Hard Rock or Goth. Never heard of goth but if I did I would expect it to have a creepy sound to it. I guess what I'm asking is do styles have expected sounds? When I play my keyboard I have styles on there that I wonder if there should be certain chords that should fit with the style... and also melody
When people talk about "Styles" of music, they might be talking about various different things. Many styles are very associated with particular sounds; other times, musical styles might be also be associated with a type of dance, or a listening demographic, or a place, or a religion, or a period of history, or a style of performance or marketing, or a clothing fashion...
It is fair to say that most styles are associated with certain sounds:
- particular timbres
- particular chords and 'harmonic palettes'
- particular types of chord progression
- particular rhythms
...and so on.
In my opinion, 'Goth' or 'Gothic Rock' actually isn't overwhelmingly associated with expected sounds - https://en.wikipedia.org/wiki/List_of_gothic_rock_artists contains a lot of bands who sound quite different from each other.
