Structure.

[GoodShot]

Please can someone tell me common structures for trap and hip hop beats?

I've been using 4 or 8 bars for everything but I listen to some songs and I'm sure I'm counting 6 bars for hooks sometimes.

I've been listening to "I mean it" by g eazy and I'm sure I'm counting 6 bars for the hook.

Do you have a template you stick to personally or just go by the feel of each song?

For me, song by song.

However, great observations - use this to inform your own arrangements and maybe sometimes copy an arrangement, see how it works see how it fits. Maybe you'll bring certain structures into your own stuff sometimes.
