Can one learn to obtain perfect pitch? If so, what would be the necessary steps to learn it?
Yes, it is possible to learn perfect pitch. A good practical way to start developing your sense of absolute pitch is to choose a single note to use as a reference pitch. Pick a pitch you can easily refer to – like a Middle C if you’re often near a piano, or the A440 of a standard tuning fork (440Hz). Then, listen to that note repeatedly until you can recognize it without any reference. You can then move on to other notes and chords.

Another way to develop perfect pitch is by doing exercises that help you connect with each sound and let it come into your ears. This practice is very personal experience and can be compared to meditation.

Playing different notes on an instrument with your eyes closed and seeing if you can recognize them by name is another great practice.
What note should I choose if I play guitar?
If you play the guitar, you can choose any of the standard tuning notes as a reference pitch. The most common tuning for a guitar is E-A-D-G-B-E (from the lowest pitch string to the highest pitch string). You could start with the low E string (82.41 Hz), or the A string (110 Hz) as these are easy to remember and frequently played.

Once you become comfortable recognizing the chosen reference pitch, you can proceed to other notes on the guitar. Remember, the goal is to develop your ability to identify pitches without any external reference. Practicing with different notes across the fretboard, and incorporating chords and intervals, will help you strengthen your sense of pitch recognition.
