The octaves of a piano are color-coded in this diagram:Ī piano contains seven full octaves, with four extra keys on the ends. Two keys with the same note but in different octaves will have different pitches. The notes can be further divided into octaves, each of which contains 12 keys. Here you can see all 88 keys with their corresponding notes labeled: The ♯ and ♭ symbols stand for sharp and flat, respectively. The remaining 36 keys are black and are used to play the accidentals (A♯/B♭, C♯/D♭, D♯/E♭, F♯/G♭ and G♯/A♭). The modern piano has a total of 88 keys, 52 of which are white and are used to play the natural notes (A, B, C, D, E, F and G). Since then, it’s undergone many design changes, eventually resulting in a (mostly) standardized key configuration. The piano traces its origins back to early 18th-century Italy, where it was invented by Bartolomeo Cristofori. Understanding the theory behind the physical piano will help us to better recreate it digitally in Unity. What Is a Piano?īefore I dive into the code, let’s explore some of the background on the piano and the musical notes it plays. Using UnityLink, it’s now possible to combine the advantages of the Wolfram Language’s impressive simulations with regards to rendering, audio and physics, with Unity’s efficient packaging of all three into standalone applications for web, desktop, mobile and console platforms. As for the last one, I opted to use the newly introduced UnityLink-a powerful link between the Wolfram Language and the real-time development platform Unity. The first two can be accomplished trivially in the Wolfram Language. A portable, interactive, real-time-rendering audio and 3D-physics engine. Because working in Unity is incredibly quick and efficient with the Wolfram Language and UnityLink, I’ve created a playable section of piano, and even learned a bit of music theory in the process.įirst, I determined that building the piano requires the following: And luckily, I had Mathematica, Unity and a few hours to spare. So naturally, it looked like I would have to build one myself-digitally, of course. For me, acquiring a real piano was out of the question I had neither the funds nor space in my small college apartment. You can see all of the submissions in this notebook.You know what’s harder than learning the piano? Learning the piano without a piano, and without any knowledge of music theory. There were 22 entries to this year’s contest, and many beyond the ones I could present here that merit a look. I’d like to point out that fully half of this year’s honorable mentions and prizes went to the father–daughter pair of Philip and Stella Maymin, a first in the history of the One-Liner Competitions. You did have one character left, Philip ) The judges commented that it would have been really nice to show the score as you are playing. With just 127 characters, Philip has created a polished, interactive and challenging game that’s actually fun to play. When you’ve revealed all the numbers, the game board is replaced by your score, which is the number of clicks you used: When you click an asterisk, you hear the number it hides spoken, and must remember what was spoken where in order to complete the game, trying to use the smallest number of clicks to do so:
