In today's music landscape, full production is generally an afterthought. Many of today's producers often do not see a project through to completion, instead they sell or rent a beat to an artist and that is often the end of contact.
In order to develop your sound and meaningful reputation as a serious producer, you must see a project all the way through. A producer must not only compose the beat either directly or via third party but they must have a vision for how the vocals must sound as well as how the mixing and mastering is done. A producer is often the coach for an artist, the same way a coach is for an athelte; their job is to get the best performance in the studio. A producer must not pass off the beat and leave the artist to do their own thing unless, they are 100% comfortable with the artist being able to rock your beat without assistance. To be fair, there are some artists that are uniquely talented enough that you can leave them alone to do their thing but their are others that have the raw vocal skills but need a little guidance to make the song pop. A producer must determine this by vibing with the artist in order to learn their personality and skill level.
If you are new to the production game, you may not feel comfortable coaching an artist or sitting in on a mixing session, but as you grow, this is a valuable asset that you must add to your skill set in order to be placed with the professionals.
I am a total music fan and enjoy working in the studio. To know me is to know music.
