Listening to songs, instruments that were used to composed it can be identified. I was advised before that to develop my focus, I can follow the sound of the bass in the song and concentrate on that. Have you tried using music for self-improvement? Aside from leisure, I think it can have a lot of applications.
Following sounds intently has helped me silence my overthinking. Although there is music for guided meditation, listening and finding the most subtle sounds has perks, such as bringing you into the moment.
It seems interesting doing this to different kinds of songs. Isn't the sound of the bass hard to follow, though? I think listening to a violin will be easier because its sound is easily identifiable compared. You can add the piano to the instruments that are easy to identify.
Focusing on one sound is supposed to be good for meditation, but I find it impossible to do. Do you guys manage to mentally isolate one component amongst the music?
I'd try to follow one instrument's tune throughout the song, but I keep losing it when different sounds play at the same time. Maybe being familiar with the sound first will help in being able to follow it.
