STAFF

STAFF

Just as the tempered system has Chinese origins, attributed to the theorist Zhao Yu, the staff is instead a European invention. Born in the medieval period, it helped spread a precise and orderly way of writing music around the world, and it is still the most widely used system by humans to read, write, and pass on sound.

Five horizontal lines, four spaces. This essential framework is all we need to indicate the pitch and duration of every note. When we write a note on the staff, we fix two pieces of information in a single symbol: what sound to produce, and how long to make it last.

PITCH

The vertical position of the note on the staff tells us how high or low the sound is. If a note is written higher up, the sound will be higher-pitched. If it’s written lower, the sound will be lower-pitched. Notes can be placed on the lines or in the spaces between the lines. Each line and space corresponds to a specific note. By looking at where a note is written, we can figure out its name and imagine its pitch.

For example, in treble clef, the bottom line represents the note E, and the space above it represents F. These notes are located in the central area of the keyboard, where sounds are neither too low nor too high, but similar to the range of spoken voice.

DURATION

By contrast, the shape of the notes doesn't affect their pitch or name, but it changes their duration over time. For instance, a note that is hollow and has no stem lasts longer than the same note with a black head and a stem. To sum up: the vertical position of a note, measured by lines and spaces, tells us its name and pitch.The shape of the note tells us how long it should be played.

SAME NOTES, DIFFERENT SHAPES

SAME SHAPE, DIFFERENT NOTES

MATHEMATICAL PERSPECTIVE

The musical staff is a visual representation of a logarithm. We perceive the segment C2–C3 and the segment C3–C4 as having the same “length.” In reality, however, between C2 (65.4 Hz) and C3 (130.8 Hz) there are about 65 Hz, while between C3 and C4 (261.6 Hz) there are about 131 Hz.

The same applies to other intervals, such as the major third: between C3 (130.8 Hz) and E3 (164.8 Hz) there are about 34 Hz, while between C4 (261.6 Hz) and E4 (329.6 Hz) there are about 68 Hz. Here too, the difference in Hertz doubles, yet the perceived interval remains the same major third.

Therefore, our ear — or more precisely our brain — does not process musical intervals through a simple addition of frequencies, but rather in logarithmic terms.

An even clearer example is the semitone: moving from 100 Hz to 105.9 Hz produces the same perceived interval as moving from 1000 Hz to 1059 Hz.

CONCLUSION

Anyone who reads music learns to see two things in one note: pitch and duration.A note placed in the second space, with a filled head and a stem, becomes a sonic image that says: this is the pitch, this is the time.That’s why reading music isn’t just recognizing symbols — it’s imagining a sound.

Written music is a map: every note you read, you can also hear — just like when you read a written sentence, and you can already hear the words in your head.
