Even if you are a man! There's a man behind this idea - sax player Ned Rothenberg, to be exact. He described his practicing as "getting pregnant" creatively. Here is the article where he mentions it.
I really admire his improvisations. He must spend a lot of the time pregnant! His CD "Amulet" with Tuvan singer Sainkho Namchulak is something else.
I drew great inspiration from it when preparing for my trip to Tuva in 2004. It was my first solo appearance only improvising, and I was happy that it was in a far and distant land. Although I don't think the concert went well, it was a very fruitful time for me - I really practiced a lot to prepare for it and took some practice notes which I use to this day. Someday I'll post about my adventures in Tuva!
Although from time to time it is part of my job, I just hate being an assembly - line flutist. Piece gets on the stand, practiced, performed, basta. Next. And so on. Although I learn pieces fairly quickly, I really don't like to. It's one thing I really can't stand about the contemporary music business. I'm also at a point in my life where I really enjoy contemplation, it would be great to spend time on my instrument pondering different interpretations of Bach, or any great composer for that matter. Or deepening my understanding of tone production and discovering new sounds. But often it's monkey-work. By that, I mean spending time churning through pages littered with excessive black dots, my trusty metronome by my side, starting half-speed and inching ever upwards.
My ideal is that I have enough time to live with a piece of music, or for it to become a part of me. This is also why I like practicing. I remember my school days in Amsterdam, practicing in my then-boyfriend's attic. He would tell me: why do you practice so much? you don't really need to! Well, I was getting pregnant. I get full of the music and then and only then am I ready to fling it out.
Lucky for us (flutists)! We now have modern "classics". I have lived with the Berio Sequenza ca. 15 years, Ferneyhough's Carceri for 12 years, Varese Density 21.5 for 10 (learned that one late!). My next solo concert (5 July) I hope to make a mostly "classical" one, along with two new pieces by younger composers. What luxury! Now to juggle time for practice, rehearsals, teaching, cuddling (baby and husband), household stuff and blogging. Dang it, I wish I had a maid, now that would really be luxury....
