I'm an electronics engineer.
My programming experience is limited to high-level Matlab/Python signal processing stuff, and low-level C microcontroller stuff.

Is there anything quantitative/qualitative about tone? Makes me think of en.wikipedia.org/wiki/Bouba/kiki_effect and that someone should do an experiment like blog.xkcd.com/2010/05/03/color-survey-results |

Why does a piano have only one or two strings per note in the bass register, but three for other registers? What if the strings were made of uranium? |

Why does a piano have only one or two strings per note in the bass register, but three for other registers? I think the amount of air moved by the strings themselves is insignificant. They vibrate the sound board, which moves the air. |

Why are there twelve notes in an octave? Actually this was known before Pythagoras. He was just the first whose followers wrote it down. Also, modern theory shows that small integer ratios are only applicable to harmonic sounds. Inharmonic sounds or sounds with only odd harmonics produce different scales. |

Evidence of Just Intonation in Recordings with Non-fixed-frequency Instruments Actually I recently read that violinists play closer to equal temperament than just, but this surprised the author and was supposed to be from accompanying pianos too much. I'll post the reference if I stumble across it again. |

Examples of songs or phrases played in different temperaments soundcloud.com/tracks/search?q[fulltext]=just+intonation soundcloud.com/tracks/search?q[fulltext]=xenharmonic soundcloud.com/tracks/search?q[fulltext]=microtonal or the same searches on freesound.org for smaller snippets |

Recommend reading why we have 12 pitches and another metrics in microtonal music? Also worth reading, albeit unnecessarily confrontational: sonic-arts.org/mclaren/partch/errors.htm |

Is there a defined note for the triangle? It might not have a pitch. Percussion instruments like bells and blocks are often non-harmonic. |

Is there a way to measure the consonance or dissonance of a chord? @MatthewRead: Beating is the cause of dissonance. en.wikipedia.org/wiki/… |

Piano tuning just under the absolute pitch Which keys did you measure? Did you take stretched tuning into account? |

Is there a way to measure the consonance or dissonance of a chord? @MatthewRead: Yeah, but according to that curve, a 2.01:1 ratio of sine waves should be equally consonant with a 2:1 ratio, yet when I test this, there is very obvious beating in the 2.01 case. Maybe this is just due to distortion in headphones? I'm not sure. |

Is there a way to measure the consonance or dissonance of a chord? "it turns out to be impossible to tune all twelve chromatic notes" In Just intonation there aren't 12 notes. There are just tones in a fractal arrangement with small integer ratio relationships. 12-tone equal temperament is an approximation of Just intonation. |

Is there a way to measure the consonance or dissonance of a chord? I believe this is called "Tenney's harmonic distance". "HD(a/b) = log(ab) where a/b is a relatively prime, usually octave reduced ratio." I plotted it here. (Does this work for chords, too? 4:5:6 is a major chord and 10:12:15 is a minor chord, so minor chord is 1.6 times as dissonant?) |
