In music your ear is the most important thing, I have a lot of friends that ask me for tips or tricks in music for them to write better music or better solos, I just tell them one thing, TRAIN YOUR EAR.
For me, is your business card presentation as a musician, not only how well you play your instrument. Developing your ear will make you a better musician in no time, you will be able to hear things in your head, translate them to your instrument or writing, you will transcribe more easily, you will appreciate production more, you will be able to recognize things in music that you can grab.
However, How do you develop your ear? In my case I took solfege classes with a personal instructor, that helped me a lot, plus the years and years I have been involved in music, hearing it, embracing it, and playing it, years and years pass and I understand music more and more everyday.
So, in what stage are you? Ask yourself, do you recognize a riff in a song and translate it to your instruments?, Can you define notes? Can you hear the chords in one song and name them? Can you translate a choir of 4 voices listening to it like 3 or 4 times? try to focus on this, this will be my most humblest and recommended musical advise that I can give!
