Unlike all other woodwind instrument you’ll find in classical music, the flute isn’t blown into, but blown across, just like a cola bottle. But the flute is much prettier to look at than the bottle — and sounds better, too. As you set that column of air inside the flute moving, it produces a beautiful, silvery sound. Here’s how the flute creates such beauty — and where to hear it.
Making music out of thin air
Monty Python fans may recall the TV show spoof in which, in one four-minute episode, the Pythons promised to resolve all wars, cure cancer, and teach you to play the flute. The instructions turn out to be “Well, you blow across one end, and move your fingers up and down the outside, and that’s how you play the flute.”
Actually, that’s exactly what you do. If you cover all the holes on the side of the instrument and blow across the hole, the entire column of air inside the instrument vibrates. This fingering produces the lowest pitch.
Now, here’s how to change notes on a flute (or any column of air you may have lying around). Keeping your hands over the instrument, open a hole near the end farthest from your lips. That hole interrupts the vibrating column of air. Now the vibrating column of air stretches only as far as the newly opened hole. In other words, the new column is shorter, and the pitch goes up.
Keep opening up new holes successively, and the column of air becomes shorter and shorter still. The pitch continues to climb.
Of course, a real flute is more complicated; it has a complex mechanism of keys to cover some holes and open others. As on most woodwind instruments, some notes are produced by various complex combinations of open and closed holes. But you get the idea.
Hearing the flute
You’ve probably heard the sound of the flute; if by some chance you think that you haven’t, well, by golly, go listen to one now. The sound that a flute makes is gorgeous.
For starters, check out some lovely flute passages. The third movement of Mozart’s Piano Concerto no. 22 (Track 03) has a very short, lively, and delightful solo for flute (1:11). And you can hear a low, haunting passage for three flutes playing together in the last movement of Tchaikovsky’s Symphony no. 6 (Track 07; 0:52).
Quite a few concertos have been written for flute solo. Here are some of the nicest ones:
Wolfgang Amadeus Mozart: Flute Concerto no. 1 in G major
Mozart: Flute and Harp Concerto in C major
Antonio Vivaldi: Flute Concerto in D Major, opus 10, no. 3 (The Bullfinch)
Gabriel Fauré: Fantasy for Flute and Chamber Orchestra
While you’re at it, take a listen to these beautiful flute sonatas:
Francis Poulenc: Sonata for Flute and Piano
Johann Sebastian Bach: Sonata no. 1 in B minor
Furthermore, you really should hear these flute solos from the orchestral collection:
Bach: Orchestral Suite no. 2 in B minor
Claude Debussy: Prelude to the Afternoon of a Faun
Felix Mendelssohn: Incidental Music to A Midsummer Night’s Dream
Maurice Ravel:Daphnis and Chloé Suite no. 2
Johannes Brahms: Symphony no. 4 (fourth movement)
