How to sharpen your hearing ability
Refine your hearing ability is a tough challenge with yourself. The exercise that I propose will repeated patiently until you are master of your mind and your ear.
Take a CD of Classical music or Jazz, performed with just 4 or 5 instruments. Choose it in the kind of music that you love. Listen to one of the songs that you already know, deciding in advance on which instrument you will practice. For example, the Piano. Mentally isolate it from other instruments ignoring them, and follow it until the end of the song.
You will understand how difficult it is performing this exercise because you will be attracted by the melody, of the other instruments as a whole. Do not give up. Rather, take a moment, and then resume the exercise. It takes two or three days to succeed in complete control of yourself only on the piano.
When you feel master of your mind and ear on Piano, only and only then you will pass to practice with another instrument of the same song. Relax yourself every now and then. You will have to perform this exercise chasing one instrument at a time, until being able to pursue them all, and separately. Not groped to exercise yourself, with more than a musical instrument a day because you'll be at the starting point. Give yourself a day of relaxation before switching to another instrument. With this technique, you will reach, the ability of a absolute pitch with goals of selective hearing, really exciting.
You will recognize the beauty of a song through his musical details.
