🎷 Instruments

Gateway to the instruments: three interactive pages, ＋two universal concepts (transposing instruments, modulation). Every stop can be clicked and heard.

🎪 instrument pages

Get to know each instrument in depth — each with interactive games and timbre demos:

🎷

Meet the Saxophone

hear all four family members · written pitch vs interactive comparison with piano concert pitch

🔁 What is a transposing instrument?

For some instruments, "what you read" and "what actually sounds" are different.B♭ a clarinet reading a written C ", and what actually comes out is B♭ — such an instrument is called a transposing instrument. Pick an instrument, then press "play the written C" to hear the difference:

what you actually hearB♭

Why design it this way?Instruments in the same family (B♭ clarinet, A clarinet, E♭ clarinets…) share identical fingerings, a player learns one set of fingerings and can switch instruments — the transposition headache goes to whoever copies the parts. So when playing with piano, B♭ instruments are written a major second above concert pitch、E♭ instruments must be written a major sixth higher to land on the same pitch.

🎚️ Modulation: the same sentence, said at a different height

Modulation＝move every note of a melody by the same distance. Hear the same original motif in different keys:

Where do you meet it? a song feels too high or too low to sing→modulation; the final section of a song lifts the emotion→up a major second (the "key change" of a pop song key"); with B♭/E♭ ensemble playing→transpose the part for them first. The golden habit for improvisers: practise the same lick in all 12 keys.

🎯 A = 440:a worldwide convention

「A=440" means: the reference pitch A（La) vibrates per second 440 times（440 Hz）。 This is 1939 at an international conference. Orchestras still tweak it, though: European orchestras often use 442–443(brighter), period orchestras use 415(a semitone lower, Baroque pitch), while most orchestras in Taiwan 440–442。

🎧 listen 438–442 the difference

440.0 Hz

What are beats (beats)?When two notes of nearly the same frequency sound together, the volume swells and fades — "wooo — wooo" — swells per second＝the difference between the two frequencies.440 and 442 sounding together = 2 times.Tuning simply means driving those beats to zero—— The slower the beats, the closer you are; when they vanish entirely ＝they are perfectly in tune. This is faster and more accurate than watching a tuner, and it is exactly how players train their ears.

🎼 Who leads the tuning? Which note?

setting	reference pitch	who gives the pitch	procedure
Orchestra	A(concert 440–442）	Oboeprincipal	The oboe is hardest to adjust and cuts through best, so it gives A → the concertmaster (first violin) confirms it → woodwinds and brass tune first → the strings tune
wind band／chamber winds	B♭(concert pitch)	the principal clarinet or oboe	most wind instruments are B♭ transposing instruments, use B♭ is most natural for everyone (B♭ instrument plays the written C）
when a piano is present	the piano's A	Piano	A piano can't be tuned on the spot, so everyone tunes to the piano — jazz combo, and recitals all use
jazz combo	A or B♭	the piano or bass	a quick check on stage and off you go, ears adjusting all the while — a jazz player's intonation is "dynamic"

Clarinettist's cheat sheet: B♭ for a clarinet to sound a concert A, the fingering is for the written B(a major second higher); to sound the concert pitch B♭, finger the written C。 a cold instrument plays flat — warming it up beforehand beats pulling out the tuning slide.
