Music Training Can Help the Brain Focus

id wager 'practicing' anything u enjoy can help ur brain focus. maybe music has a thing with emotion _and_ counting which does help more to occupy the both parts of the brain easily, but if you enjoy something this is often kinda the case. gotta occupy the rational and the other side. In some cultures, this is sort of a 'meditation through work/practice'. its been known for thousands of years by now.

if you so enjoy music: i find an instrument to be particularly effective. more so than , in my case, electronic sound production, or writing it without a physical instrument. for me the coordination and counting/keeping measure, combined with the sound following your emotions (if you get into it a bit... dont need a lot of skill). totally makes the world around fade out, and practicing it, helps also to achieve that effect outside of the practice, since each time you practice, you practice the brain muscle to be in this state.

some ppl get a dog or cat. I'd recommend a cheap guitar or so :)
