Anyone else who sings something like ‘Gaudete’ from memory at Christmas will be facing Magenta’s annual memory challenge of four verses of Latin. Doesn’t sound so very much in itself, but alongside other challenges like the rest of the seasonal repertoire to commit to heart and a reasonably sprightly tempo, it feels like a bit of a stretch.

So, here’s what we did in a 20-minute blitz to kick-start the process.

First, we assigned each verse a colour: red, green, yellow and blue respectively. We then took each verse in turn, and I asked random singers to give me a number between 1 and 12, which gave an exercise from a pre-prepared list:

Sometimes you read a book, and 20 years later you find there’s a single passage or argument that has stayed with you.There is a passage in Richard Dawkins’ book The Blind Watchmaker that’s like this for me. It’s where he’s taking on a critic of the theory of evolution who argues that the eye is such a complex and intricate organism that it could not possibly have evolved incrementally, because it would have had to go through so many intermediate stages in which it worked only imperfectly and would therefore confer no advantage on its owner.

Dawkins answer was (in my recollection):

The odds are that you are reading this through glass lenses.

Sunday took me back down to London for the third of my quick-succession visits to Capital Connection. This time we had a little longer to spend together, so we could start and end the afternoon getting into the detail of repertoire, with a presentation/discussion session on performance psychology sandwiched in the middle.

This session was based upon the one I prepared for a LABBS education day back in April, but with a longer time-frame to play with we were able to unfold the content out into longer exercises and discussion sessions en route. For instance, instead of just introducing the distinction between outcome, process and personal goals, we could spend some time discussing what kind of goals would fit in each category for the chorus at the moment.

Saturday saw choral directors from around the UK brave the winds the floods of the previous few days to come to Birmingham for the second iteration of my Conduct with Charisma workshop. As I remarked after the last one, this kind of event brings with it that wonderful ensemble quality that you learn things together that you wouldn't learn exploring the subject by yourself. Filtering the material through the different perspectives, backgrounds and assumptions that the different participants bring with them gives everyone a rounder and more nuanced understanding than would otherwise be available. The social dimension of learning is about what you can learn as well as how

I have quipped before that when testing out ideas to do with charisma, a basic acid test is to check if they work for both Hitler and Jesus. This sounds like a frivolous way of doing things, but it actually works quite well, because it takes two major figures whose stories are well known (and therefore easily accessible for thought experiments), but operating with very different moral frameworks.

A recent article in the BBC online News Magazine (written as a trailer for a BBC2 documentary series) gives a good framework for demonstrating this. It’s an account by historian Laurence Rees of the factors that led to Hitler’s popularity as a leader, intended as a cautionary tale for countries going through economic turmoil today. Its basic premise is that Hitler was unlikely leader - seen in his younger days as something of an oddball - but that a combination of circumstance and strategy propelled him into an astonishingly powerful position.

The weekend took me over to Minden in Germany, to work with a capella ensemble Oriana in advance of their Advent concert on December 2nd. They are preparing a selection of repertoire that is strongly themed in terms of text, but very varied in style and origin - from Renaissance counterpoint to spirituals.

Consequently, one of the primary areas we worked on was mood-set. The group had previously identified the starts of pieces as an area that would benefit attention - like many ensembles they had found that it sometimes took them a bar or two to really get into the flow of a piece. And a programme that propels you into a new musical and emotional world every few minutes is going to make particular demands on this dimension of your performance.

I was back in Ruislip on Wednesday for my second coaching visit in quick succession to Capital Connection. We were continuing with the skills agendas we had started last time, but - given the time of year - we did so via Christmas repertoire.

It is a commonplace in groups that maintain a performing repertoire that the skill level you had when you first learn a piece tends to get embedded in the performance of that piece. And it can be hard, therefore, to develop the performance as the skill level improves. Sometimes the reason why music gets dropped from repertoire is less about the song itself than about shedding the traces of past habits that it still contains.

Christmas repertoire gives a strange variant on this process. You start in on rehearsing it each autumn for a relatively intensive period, perform it quite a lot, and then put it to one side for the next 9 months or so. When you come back to it, it gives you a snap-shot of where you were the previous year.

After my day with Rhapsody in Peterborough, I had a day in Essex coaching Flame quartet in the morning and Chorus Iceni in the afternoon. Flame is a new quartet, though its members bring a considerable breadth and depth of previous experience to the party, while Chorus Iceni are fresh back from achieving their best results ever (by a considerable margin) at LABBS Convention last month. So there was a good sense of momentum in both sessions, if for different reasons.

With Flame, we spent a good deal of time using a new coaching technique I had actually devised the day before with Rhapsody. I have been advocating slow practice as a way to get into the detail and give yourself time really to hear the harmonies for a good long time. But this has usually been an analytical process with a technical focus, rather than serving artistic goals.
