What are modes?
In this video, I give a succinct explanation of the concepts of modes in western music theory. This explanation includes an overview of the concept, audio examples, and a slight explanation of the qualities of each mode.

Harmony, Done Visually
Переглядів 11 тис.2 роки тому
In this video, I propose a alternate way of visualizing music that has a larger emphases on representing harmony (as opposed to the regular pitch and rhythm). More visualizations are posted on my second channel: ua-cam.com/channels/rJdcopdp-Rifx_ERGwlXqQ.html Also consider subscribing to the STEM channel if you enjoy math. There is only one video up at the moment, but I have plans to make more....
The longest chord progression

In this video, I break down the "epic sequence", a fabulous chord progression that passes through every major and minor key without repeat. This progression reaches wide in the world of music theory, with connections to the circle of fifths, jazz chord extensions, and the super ultra hyper mega meda lydian (or super dark) scale.

    Bach is technically considered a part of the rococo period. The "transition" between baroque and classical methods. In fact, he was considered old fashioned during his day. Imagine Duke Ellington, composing big band music in 1990. No one would have cared. Same for Johann unfortunately. :(

    This was very well done! I've been a fan of processing for a long time / using it for years. I don't often see people making projects with it, with the exception of TheCodingTrain community members. The best part of this video was the presentation, the animations for code blocks appearing was smooth and the script was well written. Bravo!

    Nice video! As I listened to the passage it ocurred to me that the chromatic pivot chord can also be heard as a Ger6 in Em (if in an unusual inversion), which stays in the previously established tonal center. Another interesting detail I think smooths the passage is that the top C has a contrapuntal (as 9th of the chord) and tonal (as m6 of E) tendency to resolve down to B (5 of E). However, when it is reinterpreted chromatically as B# it becomes (in view of the whole phrase) a tone which still tends to resolve to 5 (C# in F#), but now from the opposite direction. I feel these kind of fragments illustrate an important reason for the adoption of enharmonic equivalence in our tuning systems, since it allows for such expressive ambiguities!

    This treatment is valuable but incomplete, indeed silent on the most important point of all. It only describes the positional relationship between notes as an ordered set treated as a group. It neglects the important point that musical notes are a notation for describing SOUNDS. Each note has a corresponding frequency and wavelength of physical vibration. Most people know that two notes an octave apart are called by the same name, so for example A440 (known as "concert pitch" at 440Hz) and A880 (880 Hz) are both called A. The reason why the fifth interval is so important musically (even neglecting the set-theoretic aspect) is that the fifth above a given note N of frequency f is that it has the frequency 3/2f. There is a physical harmonic resonance in this relationship between frequencies, just as there is for the octave of N at 2f. This has two important physical consequences. A set of objects tuned to vibrate at these frequencies will tend to vibrate sympathetically when one of them is sounded. Also, we have reason to believe that within the complex neural structure of our brains is something equivalent to a phase lock loop, which is naturally reactive to harmonic intervals. This is the most fundamental reason why music "sounds good" to us, and it's the first step in understanding why music is MUSIC and not just some interesting features of ordered sets. Taking a root note N at frequency f, the harmonic sequence begins f (root,) 2 f (octave,) 3/2 f (perfect fifth above root,) 4/2 f (octave,) 5/2 f (major third above root,) 6/2 f (perfect fifth above octave,) and then things start to sound a bit weird. A similar effect happens if we follow around the circle of fifths from the root (f,) fifth (3/2 f,) fifth of fifth (3/2×3/2 f) and so on. The fifth of the fifth is a major second interval, almost. The problem is that in a 12-tone even-tempered scale, each semitone frequency g is a factor of 2^(1/12) ~= 1.0594 greater than the previous one f, whereas the fifth interval by this method, f^(7g) ~= 1.498 f is not quite that of our harmonic method 1.500 f. If we only take a couple of steps, say the fifth of the fifth, it's close enough to fool the phase lock loop in our brain, but the further we carry it, the more audible the discrepancy becomes, hence effects such as the "wolf fifth." In other words, we can only close the circle of fifths right around through all twelve notes if we use 2^(7/12) × f instead of 3/2 f at each step. Starting at A440 (440Hz) we would not use 3/2×440 = 660Hz for the E above concert A, but instead 2^(7/12) × 440 = 659.255. I can understand why the video didn't get into these slightly hairy sound calculations, but hey, we're taking about music, and music is nothing without sound.

    At 4:20 you mix up plagal and perfect cadences. In “positive” harmony the perfect cadence is V-I, so the progression should go around counter-clockwise, while the negative version should go clockwise because it’s iv-i.

    Typical of a nerd, he speaks quickly in order to demonstrate what he knows, rather than take his time, bringing the uninitiate along for a journey where they find themselves learning. I could listen to it on 0.75 perhaps but it seems it presupposes a knowledge of at least some music theory. TL; DR I wish he had made for utter noobs

    Phenomenal! I know the last statement was a joke, "If you don't follow these rules you'll get burned at the stake" But I think it is good to emphasize that following these rules strictly is more in the nature of Baroque music and as music developed composers figured out clever ways to break free from always having to do things like approaching dissonances with stepwise motion and reserving the 6/4 for when it can be treated properly. But this is no criticism to the video itself just trying to help anyone who might be reading the comments. This is hands down the most efficient Voice Leading Video I have ever seen. It teaches people the foundational ideas and terminology and from here they can brainstorm, ask questions and do research. 😄👍
