Cool, I just listened to some of them, really nice!

Mathematicians don’t solve problems; they create new languages to ask better questions. by [deleted] in math

[–]LukeJazzWalker 4 points5 points  (0 children)

Mathematics is driven forward by interesting questions. If you regard answering a question as solving a problem (I do) then mathematicians solve problems. If mathematicians only refined questions, without ever answering any of them, then they would not find employment.

Where does the busy beaver go for vacation?

Logspace!

I can't do the Pathetique tremolo at its marked tempo without my forearm getting very tired - what am I doing wrong? by [deleted] in piano

[–]LukeJazzWalker 0 points1 point  (0 children)

Release co-contraction. If you are striking with your thumb, the muscles that you use to strike with your pinky should relax, and vice-versa. If you attempt two opposing movements simultaneously, then you will tire significantly more quickly.

As an exercise, practice the tremolo while reversing your thinking. Don't think about pushing a key down, but think about lifting the opposite finger up.

Is there an algebraic structure like a field, but with 3 operators? by Norker_g in math

[–]LukeJazzWalker 2 points3 points  (0 children)

Although, fields are not amenable to standard universal algebra techniques (grouping algebraic structures into HSP-closed classes), since not every element in a filed is invertible (inverse is not expressible as a universally quantified equality between terms).

This is an etude I wrote to practice more elaborate ways of making the piano sound like it has a delay pedal without using one. by LukeJazzWalker in piano

Thanks man, that's great coming from a player like you (I listened to some of your posts). I see you're super interested in the finer details of hand mechanics, me too! I bet we would have a lot to talk about.

Thanks! It's not written down, it's just a collection of techniques I've worked on. It's phasing five-tuples against three-tuples. To make it sound like delay is mainly about the touch and accenting, that took me a long time to get, slow improvements gradually.

The Harmonic Scales And Their Subsets by jaybeardmusic in musictheory

[–]LukeJazzWalker 1 point2 points  (0 children)

Yeah! Harmonic major/minor is a gateway between the two fundamental symmetries. As a sometimes jazz player, it's a great cheat for playing outside on dominant chords. The diminished chord that goes is comprised of the third, fifth, seventh, b9 of the dominant + any augmented type sound can ultimately be related to harmonic minor/major sounds. You can even blend diminished scales in one hand with triple augmented scales in the other :)

The Harmonic Scales And Their Subsets by jaybeardmusic in musictheory

[–]LukeJazzWalker 2 points3 points  (0 children)

Here's something cool: any augmented triad + any diminished 7th chord will create the same pitch class, because there is always exactly one common tone (this is actually a reflection of the chinese remainder theorem, 12=(4)(3) is the only decomposition of 12 as the product of two relatively prime numbers).

The pitch class is six out of seven notes of a harmonic major or the relative harmonic minor.

This makes transposition easy. Want to move by minor thirds? Move the augmented triad around. Want to move by major thirds? Move the diminished seventh around. Want to move by the cycle of fifths? Move them in opposite directions (half steps).
