Alvaro, sesión 4 y 5

Hola Álvaro, bienvenido a la página con los materiales de las sesiones 4 y 5. En primer lugar, te comparto el video con los ejercicios que desde una silla te van a ayudar a evocar el trabajo que hicimos en piso, y te va a dar algunas estrategias para relajar los hombros y los brazos, no solamente para facilitar tu postura y tu disposición corporal al tocar un instrumento, sino también para relajar esta zona y conectarla mejor con todo el tronco y la pelvis, dándote descanso luego de trabajar muchas horas en el computador, por ejemplo, o luego de un viaje largo en el que has manejado por muchas horas.



Recuerda para esta miniclase sentarte en una superficie que no sea demasiado blanda y que no tenga ruedas. Por otra parte, aunque esto sea difícil, trata de no ir al máximo, de no hacer una velocidad muy acelerada (creo que en el video yo me aceleré un poco, jeje, así que hazlo más lento que yo) y trata de observarte para revisar que no estés haciendo esfuerzos innecesarios, por ejemplo apretando la mandíbula o tensionando el cuello.

Lo importante de esta miniclase no es el rigor con el que la hagas, sino la atención que pones a los movimientos que haces y a cómo una parte del cuerpo se conecta con otra para crear la acción.

Ahora, el video donde está completa la danza que hemos estado trabajando:


Y el video donde te explico la escala de Do, que es la primera que vamos a practicar para entrar en el terreno donde se juntan armonía y melodía al mismo tiempo:


Recuerda, como recomendaciones generales, que primero estamos buscando la precisión y después la velocidad. Importante también el uso de los dedos de la mano izquierda: trata de asignar un dedo para cada traste al hacer la escala sola (cuando la haces combinada con acordes la digitación puede ser distinta para adaptarse a las posiciones de los acordes).

También, pon atención en observar qué haces cuando se te complica algo en el instrumento, cuando una nota no te sale bien, o como en este caso, cuando la escala se complica y no es tan claro lo que estás haciendo. ¿A dónde diriges tus pensamientos? ¿Cuál es tu reacción ante la dificultad?

Finalmente, te comparto un artículo sobre un fenómeno musical que seguramente te ha pasado: los gusanos musicales, esas tonadas que de pronto, sin motivo aparente, se instalan en tu cabeza y no dejan de sonar por varias horas.


Earworms: why catchy tunes get trapped in our heads

By Tom Stafford

«Earworms», some people call them. Songs that get stuck in your head and go round and round, sometimes for days, sometimes for months. For no apparent reason you cannot help yourself from humming or singing a tune by Lady Gaga or Coldplay, or horror upon horrors, the latest American Idol reject.

To a psychologist – or at least to this psychologist – the most interesting thing about earworms is that they show a part of our mind that is clearly outside of our control. Earworms arrive without permission and refuse to leave when we tell them to. They are parasites, living in a part of our minds that rehearses sounds.

We all get these musical memories, and people appear to have different ones, according to a team at Goldsmiths University in London, who collected a database of over 5,000 earworms. True, the songs that we get stuck with tend to be simple and repetitive, but it seems we are not all singing the same number one song at the same time.

Lost in music

Neurologist Oliver Sacks wrote in his book Musicophilia that earworms are a clear sign of «the overwhelming, and at times, helpless, sensitivity of our brains to music». Music is defined by repetition, just like earworms, and this might make earworms so hard to shake – they are musical memories that loop, say a particular verse or a hook, forever repeating rather than running to completion. Some people report that singing an earworm to the end can help get rid of it (others report in frustration that this does not work at all).

As well as containing repetition, music is also unusual among the things we regularly encounter for being so similar each time we hear it. Fences are visually repetitive, for example, but each time you see the same fence you will look at it from a different angle, or in different light. Put a song on your stereo and the sound comes out virtually identical each time. Remembering is powerfully affected by repetition, so maybe the similarity of music engraves deep grooves in our mind. Grooves in which earworms can thrive.

Another fact about earworms is that they often seem to have something interesting or usual about them. Although they will often be simple and repetitive bits of music, tunes that become earworms have a little twist or peculiarity, something that makes them “catchy”, and perhaps this is a clue as to why they can take hold in our memory system. If there was nothing unique about them they would be swamped by all the other memories that sound similar too.

Slave to the rhythm

If you have got a particularly persistent earworm you can suffer an attack of it merely by someone mentioning the tune, without having to hear it. This proves that earworms are a phenomenon of long-term memory, rather than merely being a temporary “after-image” in sound.

But this is not the whole story. Human memory researchers have identified so called «slave systems» in our short-term memory, components of the mind which capture sights and sounds, keeping them alive for a short time while we focus on them.

One slave system is the «mind’s eye», capturing visual information, another is the «inner ear», the part we use for remembering phone numbers, for instance. It is this second part that seems to get infected with earworms. Rather than rehearse our plans for the day, idle thoughts, or lists of things to remember, the inner ear gets stuck on a few short bars of music or a couple of phrases from a song. A part of us that we normally do not have to think about, that should just do what we ask, has been turned against us, tormenting us with a jukebox request that we never asked for.

That our minds are not a unity is one of the basic insights of modern psychology – it is the story Dr Freud was telling, and, although it differs on many of the details, modern cognitive neuroscience says a similar thing. The sense of our selves is not the only thing going on in our minds, psychology says. The mind is an inner world which we do not have complete knowledge of, or have control over.

Mind games

Fortunately psychology can provide some vital intelligence on how to deal with an unruly mind. Consider the famous «don’t think of a white bear» problem, which as it implies involves trying not to think about white bears. Try this yourself, or you can set it as a challenge for a loved one you would like to torment. This problem is a paradox: by trying not to think of a thing you constantly have to be checking if you are still thinking of it – re-invoking precisely the thing you are trying not to think of.

The general solution for the white bear problem is to do something else, to avoid both thinking of the white bear and not thinking of the white bear. For earworms, the solution may be the same. Our inner ear, a vital part of our cognitive machinery for remembering and rehearsing sounds, has become infected with an earworm. This is a part of ourselves which is not under our control, so just sending in instructions to «shut up» is unlikely to be of much help (and has been shown to make it worse). Much better is to employ the inner ear in another task, preferably something incompatible with rehearsing the earworm.

If earworms survive because of their peculiarity, the hook that makes them catch, then my prediction for ridding yourself of an earworm is to sing songs that are similar. If your mind is poisoned by Brittany Spears’ Toxic, for instance, then try singing Kylie Minogue’s appropriately titled Can’t Get You Out Of My Head. By my theory this will erode the uniqueness of the memory habitat that lets the earworm survive. Let me know if it works!
