Thibaut Garcia at the National Concert Hall

Last night I travelled into Dublin for another concert by National Symphony Orchestra Ireland, this time under the direction of guest conductor Julio García Vico in a programme of music heavy with French and Spanish influences.

The undoubted star of the show was classical guitarist Thibaut Garcia, who is French but has Spanish ancestry, who played the Concierto de Aranjuez by Joaquin Rodrigo. I’ve loved this piece for ages, and have several recordings of it, but although it’s been a familiar part of the concert repertoire ever since it was composed in 1939, I’ve never heard it played live. Last night’s performance was stunningly beautiful, one of those occasions on which it was a privilege just to be there. I loved the way he played the first movement Allegro con Spirito with poise and precision but without a hint of punctiliousness. The famous second movement Adagio gives the soloist much more latitude for interpretation, and Garcia’s version was very different from others I’ve heard. The music here evokes a sense of nostalgia, which comes with both joy and melancholy. I think in too many performances melancholy has the upper hand, but last night we really felt the joy. The final movement, Allegro gentile, contains a playful series of call-and-answer sequences set against varied rhythmic backgrounds. I adored this performance.

I noticed while he was playing that Thibaut Garcia has hyperextensible thumbs (as do I) and, as I went to the bar for my interval drink, I found myself wondering whether having bendy thumbs was an advantage for playing classical guitar. You could have knocked me down with a feather when, as I was returning to my seat after the wine break, that the man himself was sitting in the seat right behind mine preparing to listen to the second half of the concert. I couldn’t resist telling him how much I enjoyed the performance and mentioned his thumbs. It must be very irksome for an artist when strange people intrude awkwardly like that, but he was absolutely charming. After a brief comparison of thumbs, I sat down and left him alone. I was too starstruck to ask him whether distal hyperextensibility is a plus when it comes to playing the guitar. Perhaps someone can offer an opinion through the comments?

Anyway, it would be remiss not to mention the rest of the programme, which contained a great of interest. The first piece, for example, Laniakea by Camille Pépin is inspired by our Local Supercluster of galaxies which astronomers have named Laniakea, an Hawaiian word meaning “immeasurable heaven”.

The programme after the interval contained energetic and colourful performances of music from the opera La Vida Breve by Manuel de Falla, the Capriccio Espagnol by Nikolai Rimsky-Korsakov and, for the finale, the famous Bolero by Maurice Ravel. All these were played very well, but the first half was so wonderful that it was always going to be impossible for the second half to match it.

On Bendy Thumbs

My thumbs can bend backwards about 90 degrees, a property known as distal hyperextensibility or, less formally, ‘hitchhiker’s thumb’.

I don’t know of any particular advantage or disadvantage of having bendy thumbs, although it does make holding a clarinet or soprano saxophone a little awkward, as the thumbs are used to support the instrument when it is played. The only useful thing I can think of is the comedy value of seeing people freak out when they see the bendy thumbs in action.

I don’t think this ‘condition’ has been studied very much, but I am given to understand that somewhere between 15 and 30% of the population has bendy thumbs. The property is inherited and is commonly believed to be controlled by a single gene with two alleles, one for ‘straight’ and one for ‘bendy’ ; the one expressing bendiness being recessive explains why straight thumbs are more common. I now realise, however, that this is not the case. For one thing, it seems that thumb bendiness is not a simple binary property. That also makes it difficult to define it for statistical purposes: what angle of bend do you choose to classify a thumb as bendy?

I also have blue eyes, which is another recessive trait, but it has been known for some time that eye colour is not controlled by a single gene.
