russian riddles

The Anna Karenina fix

Viv Groskop

Harry N. Abrams, 2018
Penguin 2019

It may be an age thing, but I am finding myself reading memoirs a lot, and maybe even writing some. Obviously I’m not all that interested in reading how people got rich and famous or how they changed their diet, but there is a sub-genre that I find really exciting, balancing cultural issues I’m interested in (literature, languages, music, art) with the life experience. So it's about how people interacted with cultural things and it helped them find out who they really are.

An important example and possibly the reason for my new interest is Elena Lappin’s memoir about her family and her five languages (What language do I dream in?). Eric Siblin mixed 1/3 memoir with 2/3 biographies of more famous people (Bach, Casals) to paint a picture of the cultural monument known as The cello suites. Then again, I'll also accept an old house as a cultural asset, see Hancox by Charlotte Moore.

I recently noticed that Viv Groskop has a new book out about French literature, and as I am a bit careful about what Anglophones write about all things French, I opted to check her earlier book about Russian literature first. It turned out to be a fine addition to my new favourite memoir sub-genre. While discussing 11 works by 10 major Russian writers (Tolstoy gets the first and the last word), she applies the philosophical insights to be gained from these books to her own coming of age and finding her identity. In a nutshell, based on her unusual name she thought she might be of Russian origin and therefore went on to study Russian and aspired to become Russian, but in the end her migration background turned out to be something else entirely.

This is arranged as a clever little puzzle, or maybe as a set of Russian dolls. Can’t be quite sure as I read the chapters in the wrong order, first those about the books I’ve read (long ago), and then the rest, not necessarily in the right order, as I was more curious about some of the works discussed than about others. But in the end it was all exciting enough to make me read all the chapters so all good and riddle solved. (Here is a photo of the Groskop family of 1915 including info about their origins, if you want to find out without reading the book.)

At some point, I think I’ll read the French book too. Another book-related memoir is Lucy Mangan’s book about children’s literature, Bookworm. And I need to read Hadley Freeman's House of Glass.



I like the cover, too.

For bacteria, a small genome means some serious decluttering -- even in the ribosome
Researchers have studied the genomes of some 200 strains of bacteria to determine which proteins in the ribosome, part of the key cell machinery, can be safely lost and why. Research showed that frequently lost ribosomal proteins tend to be placed on the ribosome surface, where they usually have fewer contacts to other ribosome components. Yet since ribosomal proteins are in the cell's essential toolkit, they are generally among the last to leave a 'downsizing' bacterial genome.
Funny though that in mitochondria we see the opposite - new proteins being added to a ribosome that has become virtually useless, producing fewer proteins than it needs for its own assembly. See my recent feature here.

planting trees

Open Archive Day

Planting some trees is (almost) always a good idea, but if we want them to help us out with stopping the climate catastrophe, we should do a bit of thinking before reaching for the shovel.

In my feature last August I rounded up some good and bad examples of reforestation, to give an impression of the complexities involved. The feature is in the open archives now:

How to bring back our planet's forests



If humans weren’t interfering, around two thirds of the ice-free land surface would be covered by trees. Restoring a fraction of the missing natural forests would sequester enough carbon to keep climate change within the limit of the Paris accord. (Photo: jarmoluk/Pixabay.

Herbivores, not predators, most at risk of extinction
One million years ago, the extinction of large-bodied plant-eaters changed the trajectory of life on Earth. The disappearance of these large herbivores reshaped plant life, altered fire regimes across Earth's landscapes, and modified biogeochemical cycling in such a way that Earth's climate became slightly colder.

colourful characters

I spotted an interesting book review in Current Biology - Thinking like a parrot - and realised that this was a topic about which I haven't written a feature yet, so I closed that gap with a little help from Nicky Clayton (who starred in this feature) and her colleagues. Oh, and I should mention that I found a lot of inspiration on the ecology/conservation of parrots in the grrlscientist blog.

After the cats and mice, another fun topic, but world-saving services will resume soon.

running slowly

A courante is a running dance, of course, supposed to be played fast. In my effort to learn the Courante from the first cello suite, however, I don't think I'm getting past walking speed. Works for me - more time to appreciate the music - but don't try dancing to it.

The other problem with the courante is that it has more notes than I can memorise in a month, so I got about half way with memorising it. So I can play the movement at half the required speed and can play half of it from memory. Count it as a half-way success. Incidentally, I note that the person who used the score before me also made fewer annotations to the courante than to the other movements I have played so far. May have been running out of steam too.

Well, anyway, moving on, or rather backwards within the first suite, we now come to the Allemande.


Resources for this movement:

A slow version from Cellopedia is a helpful starting point as the fingerings are clearly visible at all times. And he plays at a speed that even I can manage (judging by the length of the video, it appears to be 2/3 the normal speed).

For a performance at the proper speed, try this recording from Denise Djokic.

And then consider the helpful hints from Inbal Segev. She's done a short tutorial (or two in some cases) for every single movement.Underneath this one there is also a list of helpful links and resources regarding the suites in general which I hadn't seen before.

Bonus material: A lovely arrangement for guitar played by Ana Vidovic

I'm also adding these videos to my youtube playlist "cello repertoire".

Telemann's dozen

Two years (and a bit) ago I learned to play Telemann's fantasia No. 2 in a minor, which must have flicked a switch in my flute brain, as I have been playing a lot of unaccompanied baroque pieces ever since. In May, with the lockdown going on and flute lessons being off, I decided on an exploratory run through the remaining 11 fantasias, trying each one for a week, to see if I find one I want to spend more time with. I'm now in the last week of the project, so I have played every note in this lovely book, although not necessarily at the right time:



Oh, and I have added a version of each to my YouTube playlist with flute repertoire.

I have already earmarked No. 11 G major for further study, might also consider 6, 8 or 9. Number 9 is in E major (4 sharps, ####) but what I learned from it is that the fourth #, namely D#, is actually making life easier compared to playing ###, as you don't have to lift the little finger coming down from the E to play the note below. (Obviously, I haven't practiced all of my scales, otherwise I would have known that.)

Here are some interesting thoughts on the fantasias from Rachel Brown, who also has released a CD with the complete set.

Any flute players out there, tell me which one is your favourite?

PS Various artists have identified dance forms in the movements. None of them is marked in the score so I'll add to the list here whatever I can find:

1. Fantasia in A major (Vivace – Allegro=Passepied)
2. Fantasia in A minor (Grave – Vivace – Adagio – Allegro)
3. Fantasia in B minor (Largo – Vivace – Largo – Vivace – Allegro=Gigue)
4. Fantasia in B-flat major (Andante – Allegro=Polonaise – Presto)
5. Fantasia in C major (Presto – Largo – Presto – Dolce – Allegro – Allegro=Canarie)
6. Fantasia in D minor (Dolce – Allegro – Spirituoso=Hornpipe/Rondeau)
7. Fantasia in D major (Alla francese=including a Rondeau – Presto=Folk dance?)
8. Fantasia in E minor (Largo=Allemande – Spirituoso – Allegro=Polonaise)
9. Fantasia in E major (Affettuoso=Sarabande – Allegro – Grave – Vivace=Bourrée)
10. Fantasia in F-sharp minor (A Tempo giusto=Corrente – Presto – Moderato=Minuet)
11. Fantasia in G major (Allegro – Adagio – Vivace – Allegro)
12. Fantasia in G minor (Grave – Allegro – Grave – Allegro – Dolce – Allegro – Presto=Bourrée)



PDF sheet music is freely available, eg from flutetunes.com, from where I also nicked the bourrées and rondeaus that weren't specifically assigned in Rachel Brown's essay about the fantasias.

playing cat and mouse

After the Covid communications feature, I needed a little bit of light relief and was very grateful to discover through the twitter feed of French newspaper Libération a recent paper about how mice became associated with human settlements. Obviously, once we had mice in our houses eating all our grain provisions, we also needed cats. Libération referenced an ancient story about cat domestication from the 00s, but I was sure I had seen something more recent elsewhere, and I found it, and so I could close the circle of life: humans - grains - mice - cats - humans. That was very satisfying, and it fits in really nicely with lots of earlier features I wrote about things like the evolution of agriculture, the Indoeuropean languages, dogs, Bronze Age civilisations, and more.

So, great fun, and I hope you enjoy it too.
