Music 音樂
Music is sound that people have shaped. This series starts with a single vibrating string and climbs, one question at a time, to scales, instruments, and the music of many places.
音樂是人把聲音一點一點塑造出來的東西。這個系列從一根振動的弦講起，一次回答一個問題，一路講到音階、樂器，以及各地的音樂。
Every lesson has a model you can touch and a sound you can make yourself. All of the sounds are made by your browser, one tone at a time, so there are no recordings and nothing to download.
每一課都有可以動手的模型，和你自己能發出的聲音。所有的聲音都由瀏覽器一個音一個音合成，沒有任何錄音，也不需要下載。
Music words come from many languages. Where a term comes from Italian, you will see the Italian word beside the English and Chinese. Please start with the volume low: the series starts quiet and you can turn it up.
音樂的詞彙來自很多種語言。有義大利文來源的術語，會把義大利文和英文、中文並列。請先把音量調小：系列的聲音一開始很小聲，你可以再慢慢調大。

Four Sides of Sound 聲音的四個樣子
Pitch, tone color, beat, and the words for loud and fast: the four things you notice first when you listen to any music.

Why Are Some Notes High and Some Low?
為什麼有的音高、有的音低？Slide the bridge of a one-string instrument and watch the string shake faster or slower while you hear the note change. Find out why half a string sounds exactly one octave higher.推動單弦琴的琴橋，看弦振動變快、變慢，同時聽音高改變。再看看為什麼弦短一半，音剛好高一個八度。Start the lesson · 開始上課 →Why Does a Piano Sound Different from a Violin?
同一個音，鋼琴和小提琴為什麼聽起來不一樣？Pluck a string in the middle or near the end and watch it shake in many ways at once. Then mix the harmonics yourself and hear how the same note changes its color.在弦的中間或靠近一端撥一下，看它同時用很多種方式振動。再自己混合諧波，聽同一個音怎麼換了顏色。Start the lesson · 開始上課 →What Is a Beat?
拍子是什麼？Start a pendulum metronome, change its speed, and count the strong and weak beats in twos, threes, and fours. Then tap along and see how close you land to the beat.啟動擺錘節拍器、改變它的速度，數一數二拍、三拍、四拍裡的強拍與弱拍。再跟著敲，看你離拍子有多近。Start the lesson · 開始上課 →How Do You Tell a Musician “Louder” or “Faster”?
