I know all of this, but hearing you explain it is like seeing the first sunrise. I am stunned at how wonderfully clear this study is, and I am inspired.
The graphic you show at the end is genius! It makes so much sense when you see it this way. It's analogous to the 3 act structure in story telling (separation, initiation and return) Joseph Campbell talks about. And the dissonance is nothing but our body interpreting geometry of the soundwaves as "wrong" therefore drama or tribulation in the journey, same for the opposite scenario, consonance = gratification and goal reaching. Amazing video!
This is great explanation of tonal harmony. In another comment, someone says that unstable notes sound stable to him in the context of another chord than the I chord (say the V chord). That is because those notes are chord tones, meaning they are notes of the current chord. Therefore they are consonant notes in relationship to the current chord. The tonal harmony theory is great to understand tonality and chord progressions. But I think it falls short when describing how a melody note (or any note of SATB voices) sounds relating to the current chord being played. The "chord tone / non chord tone theory" is complementary to the tonal harmony theory. Our ears hear notes in two contexts : the tonality of the piece AND the current chord. (I think the last part is left out of many music theory videos and it took me years to understand how important chord tones and non chord tones are).
Thank you very much! This video and your other related videos finally put it all together for me. Maybe I was just ready, but I think it is mainly because you did such a good job in the step-by-step clear explanations that really made it sink in. Thank you, and I look forward to anymore educational videos on this subject that you feel inclined to share.
thank you so much! this is a great video! I think every one who wanna know more music theory/ structure/ construction, should watch this! I mean~ should READ this! This video is very comprehensive which makes a big leap in my music journey!!! once again, thank you so much for your gift!!!
Because in tonal harmony its about the tonic ,and by that the 4 has the 3 nagging at its side,otherwise they're both perfect, the resolve should be alike
Great video/ I personally could not "hear" in the Bach work stability and instability--to the extent I did I found the unstable notes sounded the most stable/
That was true for me as well, but I think that is because, unrelated to the root chord, those chords would work very well on their own, especially since they're major chords.
If the mind perceives simple ratios of frequencies as more consonant, shouldn’t the fourth, which is close to ratio of 4/3 with the tonic, be perceived as having less dissonance with the tonic than the third which is close to a frequency ratio of 5/4 with the tonic? The video says near the beginning that simpler ratios are more consonant, but later on says that the fourth is highly dissonant with the tonic. If an interval of a fourth is “highly dissonant”, why is is also called “perfect”?
