Higher Ground

Holy crap, they did it - inspiration has truly entered politics during my lifetime.

While searching for some feel-good videos on google video, one search culminated in the combination of Stevie Wonder and Barack Obama...


Feel gooooood....



Then.... feel great.

Les Espaces Acoustiques

This music makes me so happy.

Gérard Grisey - Partiels from La Espaces Acoustiques



Only an excerpt, and the YouTube fidelity leaves something to be desired. But it stimulates the imagination. I heard a (maybe false) story that Stravinsky kept a muted and out-of-tune piano in his studio where he composed. It was kept in this condition so as not to impede on his own imagined sounds.

I have to admit that I love the "tree of knowledge" image at the beginning of this fractal music video. Add in some imagined vibrancy to the colors and it is pretty beautiful.

Frenchy Froggy Froggy Frenchy Frenchy Frog


OK, I admit it. My two favorite sets of Chansons are Ravel's Chansons Madécasse and Trois poèmes de Stéphane Mallarmé.




That's it, I'm learning French.




I might change my mind to include Messiaen's Poèmes pour Mi or Debussy's Trois poèmes de Mallarmé.

Ask the Expert


Q: If zebra finches learn their song by imitation, shouldn't there be very little song diversity? And if so, how can the females judge the males' songs if they all sound the same?

A: Wow-that's an excellent question! It seems that zebra finches do not like to have a song that is too similar to that of other males. For example, if five male siblings are tutored by their father, only one or two of them will accurately imitate his song-the rest of the siblings diverge and sing different songs. There is an interesting parallel to this effect in population genetics. It is called evolutionary stable polymorphism: For example, different people have different hair color, and this diversity persists over many generations. If most people find one hair color (e.g., blond) more attractive, how come blond people are not becoming more common in each generation? One mechanism that can preserve polymorphism is called "frequency dependent selection," for example, blond hair is not considered as attractive in Scandinavia, where it is very common. Back to songs, polymorphism of songs in a group might be a result of frequency dependent imitation (young birds selecting some rare sounds from their tutors) or frequency dependent sexual selection (females preferring songs with some rare qualities, while some juveniles prefer to imitate their fathers).

Keep asking questions,
