Have a diverse catalogue – one of the strengths of sync is that it presents opportunities across every genre. The tricky thing is that each film/game/media production will have different needs, so there can be a lot of waiting for the right production to be made that can fit your music in.
Vampr Publishing does a lot of that hard work for you by keeping an eye on new projects being started and what Music Supervisors are assigned to these projects before pitching. However, your catalogue still needs to be diverse. One way of doing this if you only work within the constraints of particular genres is make sure that your lyrical themes are diverse, and that you are writing music that would be useful in different types of media and scenes. For example, you might write and record some music to advertise certain products you think your music works well to represent. Or, you might make music with a lyrical narrative that could fit a scene you know films are likely to have, such as wedding scenes or high speed driving scenes.
Collaborate to expand the difference genres you work in – if you know you have gaps in your catalogue you can’t fill on your own – like you need wedding music but you make aggressive Dubstep or Trap, consider working on a softened version of your sound and collaborating with a singer songwriter who can write about wedding themes over your track. This presents an interesting twist on the theme which will hopefully cut through and increase attention to your song.
When it comes to sync representation partners, either work with somebody who specialises in your genre, or stay non-exclusive and spread your bets across multiple non-exclusive partners.
