- - - What is a ChromaTone? - - -
There are 12 ChromaTones. Each ChromaTone is a Shepard Tone corresponding to one of the 12 pitch classes found on a modern (ie 12-TET tuning) piano / guitar /etc. Chroma is the Greek for colour. You will find any piece of music can be played using only these 12 colours -- and you will recognise it instantly.

- - - What is the illusion? - - -
Keep walking round the circle. Each note is clearly a semitone higher than the previous. yet after you have completed 1, 10 or 100 circles you realise the sound of each ChromaTone is constant.

- - - How does this help learning perfect pitch? - - -
I'm fortunate to know someone with perfect pitch. Through talking with him I discovered that when here's a note he hears primarily the pitch class, or Chroma; he resolves the note into one of these 12 pitch classes and hears the 'chroma' of the note. As a secondary movement of the brain he figures out where on the piano this note is.

The Shepard Tone is a perfect representation of the concept of pitch class. It has not been possible until the digital era. This is the cutting edge of music evolution.

Of course it is going to take more than this representation to acquire perfect pitch. I am currently developing a set of training games that use this framework. Check out the web link!

- - - Why have you given a new letter to each note? - - -
This is not the question. The question is: why was this not done 400 years ago when the modern 12 tone chromatic scale was conceived? This is the first of many public offerings from me... if life gives me the grace to continue my work, I'm going to build a complete musical system from this basis as well as a set of training tools. click on the ' support URL ' and look on my 'Toneme System' if you are interested in this work.

PS I'm amazed to see I have one one-star review from the US store, someone is angry. I have worked long and hard to create something beautiful and I am giving it away for free. and this seems to have infuriated someone?! The psychology of some people beggars belief! I am not claiming any invention that is not my own. The Shepard Tone speaks for itself. One has only to put 'Shepard Tone' into Google. And I have clearly mentioned both here and in the application itself that I am using Shepard Tones?! And on my website I address all of the issues related to the various tuning systems that have evolved through history. I specifically say in the application FAQ ' this topic is too big to go here, if you are interested, go to my website or contact me! '.

I am really enjoying this. Very strange approach to music for this uneducated ear but I am learning and making connections already. I don't know if I will achieve perfect pitch but if my understanding off sic deepens I will be very happy. Thanks.

Stop claiming you came up with this wonderful new idea when the guy who invented the shepards tone is still alive and won international science awards in physics and social sciences, go visit him at Stanford. Your responses to the questions are uneducated, no response to the thousands of temperament out there, or the actual science of combining frequencies for an audible allusion. Adding color to this? People started doing this to harpsichords in the 17th century, go read the first few chapters in Newton's Optiks, he puts light frequency to tone frequency. Or the 4 organs made to produce tone-light in between 1850 and 1930. Please educate yourself before trying to educate others :)


I Love it

Beautiful work of art! The color the sound and the idea behind it! Bravo! Please don't do like some of these other developers do. They try to improve on their graphics and end up screwing up the colors and making them look like crap. Trust me, it's good.


Sad
: ?

There's no sound at all.


Hmmm.

Tough to rate. App itself is beautifully implemented, but content is completely arbitrary and baffling (I'm a pro classical musician). Dev calls the content "radical" and "a quantum leap." :/ I think this app's only practical usefulness is to illustrate how interesting Shepard tones are (which it does very well). If you're a beginning musician, please be aware this app shows one person's completely non-standard novelty system that will not let you communicate with other musicians.


Wonderfully Intriguing

Pleasing on the ears and eyes, this well put together little app is curiosity-inducing and sure to make you think a bit if you have any musical inclinations. Good luck and keep up the great work, Pi!


fun

Fun to play with.


Amazing

Reminds me of Edward Maryon's Marcotone system.


I love this app!

Thank you for making this app free! I use this app to train my voice . I think it's a lot easier to hit circles than rectangular piano keys on the iPad. I will definitely check out other apps by this developer!
