It doesn’t matter what DAW (digital audio workstation) you’re using. As long as you can send a WAV file, it doesn't matter what you’re using to record. We can also use OMF files, too, but WAV is the best to use for quality purposes.
Unfortunately, MP3's are a compresses file and lack quality. Even though they’re easier to upload, they don’t have the audio information or quality you need for a professional mix.
Be prepared. Play with a metronome. That little tip will save you in the end.
If you've never recorded with a metronome start now. Practice, practice, practice, practice with a metronome. Once you have this down, practice your parts over and over. That allows you to maximize your time and budget while your project is in studio.
The structure of the song is a very important part of producing a song. I’m not talking about how the song is written from start to finish (verse, chorus, verse, chorus, bridge, chorus, chorus). It's not about that. It's about: (1) what makes sense and (2) what feels right. The structure doesn't necessarily have to make sense, but it needs to intentionally lead someone’s emotions somewhere.
