Nothing comes from nowhere. Music you hear betrays its origins; occasionally obviously, often without the composer's intent, mostly elementary—in small segments. To identify the character of music (music-tally) from its components can require luck.
You may be as lucky as Derek Paravicini. He doesn't have to see music to understandingly reproduce it—in fact, he can't—unluckily, he is blind. You may be unlucky to have been told you can acquire perfect-pitch by buying a programmed-learning course from someone lucky enough to have perfect-pitch.
Luckily, with our advancement in access to information, we have started to understand the science behind what makes us different, and that perfect-pitch is not studied—it is inherent. Unluckily, we are learning that, what is making us different is our advancement—which finds us craving luck, and finding luck, and finding its opposite—comprising a split: Derek's split may be more extreme—musical gift/social disability; many of us will only have a concurrent good-day/bad-day; while our species becomes gratified/endangered by us obliviosly accelerating evolution.
Somehow, though, we all feel music enough to value it, and for those interested in seeing what others can hear, a visual enhancement is needed. David Henningsson's Ackord (version 0.3 required) software was written for a Windows PC connected to a MIDI Keyboard.
lifetally.org supplies a chords.txt file which goes into the same directory as Ackord1.exe (replacing David's chords.txt), allowing you to see an image like the one above by holding-down a key for every degree on the Harmonic Minor scale, also allowing you to see: there is only one 13th chord in a major scale; how few fingers you need to play a 9th chord; why you can't play a 13th chord on a 6-string guitar; and much more...even where tonality ends.
