Show HN: Chord Progressions
When you realize how the current &quot;mapping&quot; of piano keys makes everything confusing and how it historically developed, it looks like musician version of &quot;JavaScript&quot;, i.e. a really crappy standard, where you can do anything but in a really unpleasant way. Map your scales directly onto launchpad&#x2F;push&#x2F;circuit, and you never get a wrong note. Moreover, the equal temperament makes all sounds slightly disharmonic, so even a professionally tuned concert grand piano sounds rather bad and unauthentic, different to what original classical composers intended (they used harmonic tuning where transposing by one key changed harmonics completely unlike with prevailing standard today). If you do acid trance, it&#x27;s OK though.
