What is the tempo of minuet?

I am learning to play Leopold Mozart’s Minuet in D-minor. Examples of the music can be found here:

• https://soundcloud.com/hudson-shires/minuet-in-d-minor-by-leopold
• https://www.youtube.com/watch?v=na4f9ltv2Fk

Regardless of the recordings, the question I have is how fast should one play a minuet?

Clearly, this is a baroque dance music. So the answer to the question will be the same as the answer to “how fast is minuet dance?”

It turns out, it’s quite fast: about 112 metronome beats per minute.

Sources:

• https://www.youtube.com/watch?v=oPYCuzcJioU - an excerpt of a BBC documentary where a historic dances historian counts to demonstrate the dance steps. It’s rather fast. Matching that speed to the metronome of my piano turns out at arounf 110 bpm.
• http://www.janvanbiezen.nl/frenchbarok.html Jan van Biezen’s analysis of historical literature shows that minuet tempo is about 106-112 bpm. The article is generally a solid source for tempos for French baroque dances. Useful for future reference.

Seriously: you want to train me to fight, to do all this stuff, but my guardian angel should be Bambi?
…
I can do rather more than that. My hiding place is an old Resolution-class submarine, 425 feet long.
…
these boats were part of United Kingdom’s nuclear deterrent programme armed with sixteen UGM-27 Polaris A3 nuclear missiles.
From here, I can burn cities. Let’s see Bambi do that.

Playing piano with body weight and martial arts

Yesterday my piano teacher showed me how to play piano with body weight. The idea is that to achieve a full and colourful tone, one should not play just with arms and fingers, but rather with the full body weight as if leaning with the upper body on one’s fingertips resting relaxed on the piano keyboard. I do not fully internalised the concept, nor can I perform the technique (that’s exactly the point of learning, right?), but I do understand what it means.

Weight transfer in piano play & exercises

Later in the evening I looked some articles and YouTube videos explaining the concept. There’s plenty of materials explaining what it’s all about: https://www.youtube.com/results?search_query=piano+play+with+body+weight

The take-away is that this is called weight transfer and there are many exercises to train it. The idea is to create a suspense bridge (feeling) between the upper torso and fingertip, use free-fall drop to play keys and effectively learn to transfer weight between fingers, instead of using force of finger muscles or arms.

This will of course take (probably long) time to develop.

But the concept is not unfamiliar, actually it very much resembles the use of body core to enact movement in Japanese martial arts.

Using your body efficiently in Japanese martial arts & sports

I am only familiar with some (beginner level) swordsmanship-related techniques from Iaido, Kendo, Aikido and Bojutsu. I also know that what I am going to say applies to Karate too. One of the things they teach, is that to deliver a really powerful, controlled and effective strike (be it with hand, or sword), you should use your hara, that is, the power of the hips, the body core. Simple interpretation without all the esoteric garbage is that it is the hips which generate body powerful rotations and thus generally provide momentum in body movements (hara-centric methods). My subjective understanding of this is that the rest is the question of transferring that momentum into useful energy delivered by another body part, typically limbs (strikes using arms, kicks using legs, or throws using the upper torso).

Similar techniques can be found at the core of many sports/moving body experiences. Another thing I am familiar with is running: again the proper technique is all about body core and hips as the engine providing the momentum, legs are to deliver it to the ground. The rest is structural, or dynamic support. Or take gymnastics and especially aerobatic gymnastics. Use of body core and hips everywhere. And so on…

Putting it together

So if I know (to an extent) the experience of using body core for martial arts, how can I transfer that same feeling into piano play?

And in turns out, I am of course not the first one to figure out the connection between weight-based piano play/weight transfer and martial arts. There is this marvelous site , where the author makes the same point in <https://pianodao.com/2015/10/31/piano-technique-weight-in-motion-boxing-taichichuan-and-the-cherry-tomato/>. Specifically:

maximum efficiency with minimum effort.
– Kanō Jigorōi about judo/https://en.wikipedia.org/wiki/Kan%C5%8D_Jigor%C5%8D

• the slow/fast judo throw video shows very well (if you are attentive) the use of hips during the throw.

The role of the muscles is to help the body maintain an efficient structure – so we can use and apply body-weight-in-motion.

This will need more elaboration till I get this right…

Open and very useful twitter thread on how a guy built a product (a to-do app) and then lost competition with a well funded VC-backed competitor (who told them in advance).

The crux of the story is perhaps: “to start something is one thing, the difficult part is to know/determine when to stop”.

Over the last weeks, I came back to the idea of fox vs. hedgehog by Isaiah Berlin (https://en.wikipedia.org/wiki/The_Hedgehog_and_the_Fox): “a fox knows many things, but a hedgehog knows one big thing”. In the past I thought my thinking is more of the hedgehog type (rather axiomatic, tree like structure with a deep root). The thing with such assessments is the problem of meta-self-cognition: what you are vs. what you think you are vs. what you like yourself to be.

Over the past year I started to write notes, at times even an intermittent diary for a couple of days, sometimes weeks. I discovered that my mind perhaps is not behaving like a hedgehog type after all. In retrospect, my notes are scattered pieced of memories, loose tidbits, quips, quotes, metaphors I come up with, or I read. The thing is, however, that I seem to be quite good in connecting those independent dots. Disconnected thoughts and scraps of stuff collected at around the same time tend to take a shape of a connected network of thoughts which then mold and over time grow into a interconnected network of bigger thoughts. All that, however, happens mostly intuitively, not as a directed effort - although at times that too, when I focus on studying some topic of actual interest of mine.

So what is it? It seems like what a fox would do: many loosely connected things which over time seem to take a shape of a deeper rooted tree. It seems after all, my mind seems to meander and bounce between the two sides as it sees actually fit. A fox which desires to become a hedgehog one day?

It helps to have a story, but it is not always possible to control what that story is.

The character Konstantin Kyriakos in that book is like a walking library of quips. The writer apparently had a collection of witty pieces and he then wrote a character around them 🙂 .

You should not be distracted by anything, you infant. When you work, you work. Does f*cking SEAL Team Six get distracted by Twitter? No. Why not? Because they focus. They have discipline. They know that what they do has consequences. People will die. Well, here’s the news: the same is true of us. Money is life. Poverty kills. If you are going to get distracted by our computer, you don’t deserve our job.

How fear modulates our perception of others

When we get into relationships with people, be they platonic or romantic, we tend to look for the similarities we share; so we find that person attractive, but we also find appealing “the complementing differences we have”.

But when fear enters the stage:

“Fear … distorts our perception of that other person, and we start to look at people as a problem rather than a person.” You also stop seeing those similarities you once saw, the things that brought you together; all you can see are the differences, which have become a threat.
– John-Paul Davies, via The Guardian

Limits of folk psychology

Folk psychology (https://en.wikipedia.org/wiki/Folk_psychology) helps us in everyday life a lot. It’s a useful heuristic. It allows us to reason about ourselves, about other people and our relationships to them. It successfully takes us through maybe 90% of life circumstances. But then it tends to shows its ugly face. It sometimes leads us to dark swamps and we get stuck. Some earlier, some later, lucky (or naive?) ones who avoid the murky waters completely. It seems to be a function of how screwed up we emerge from our childhoods (thanks parents!) and the amount of life experience we collect over time. And it is the discipline of real expert psychology which then leads the way out of the swamps of misery back to sunny beaches and green islands. And some manage, though some remain in the swamp for too long causing them a lot suffering and again some remain there unhappy for the rest of their days. Perhaps one of the long-term goals of navigating life is to attempt not to end up in that last group.

How to price your SaaS product

(summary of a blog post)

https://www.lennysnewsletter.com/p/saas-pricing-strategy

This is a very useful 101 on SaaS pricing. Provides many good insights, worth
further study and referencing.

In the beginning, the actual number you’re charging isn’t that important

Care for the magnitude. 5-10-100-1000-10k?

Step 1: Determine your Value Metric

What are we charging for. Also, be wary of the revenue “under the curve”.
Flat boxes “Good-Better-Best” are often not advantageous enough. Focus on
metric which scales with your customers.

Step 2: Determine your customer profiles and segments

Be extremely aware who is the buyer and how they tick. The guy provides a
useful template for analysing the persona. It goes beyond what I saw on other
canvases, so it might be a useful analytical tool.

Step 3: User research + experimentation

1. Priority 1: Foundational [See above]
   • Core customer segments
   • Value metrics
2. Priority 2: Core
   • Order of magnitude price point (are you a $10 product vs. a $500 product)
   • Positioning and value props
   • Packaging
3. Priority 3: Optimizations
   • Add-on strategy
   • Specific price point (are you a $10 product vs. a $11 product)
   • Price localization/internationalization
   • Discounting strategy
   • Contract Term optimization
4. Priority 4: Growth accelerators
   • Freemium
   • Market expansion (going up or down market)
   • Vertical expansion
   • Multi-Product

Some other data

1. You should localize your pricing to the currency and willingness to pay of the prospect’s region
2. Freemium is an acquisition model, not a part of pricing
3. Value propositions matter oh so much
4. Don’t discount over 20%
5. For upgrades to annual discounts don’t use percentages and try offers
6. Should you end your price in 9s or 0s? Depends on your price point
7. You should experiment with your pricing in some manner every quarter
8. Case studies boost willingness to pay quite a bit
9. Design helps boost willingness to pay by 20%
10. Integrations boost retention and willingness to pay

Never underestimate the power of focusing on the customer through research. You should never, ever just do what they ask, but you need to be an anthropologist who knows them better than anyone else.

Dolly Parton - The Grass Is Blue

How much can a heart and a troubled mind take
Where is that fine line before it all breaks
Can one end their sorrow
Just cross over it
And into that realm of insensitive bliss
