i am a composer of hip hop songs. As opposed to rap songs, hip hop songs are very melodic by nature. now sometimes i get inspired by someone else's tune, or write my own tune and then find out someone wrote a similar tune too. When you look at melody there is:
- sounds (or instrument)
- length of each note (which can be different between the notes)
- sequence of the notes (which note comes after which note)
My question is across these, how many things have to be different to show it is similar?
Also specific question about number of notes- lets say i have same sequence, almost same volume and length. how many notes before it becomes theft? 3? 5? 7?
I am choosing US because most of the hip hop songs are in the US. But i am in the UK. But I'm trying to make songs that work for the US too.
