Notes and note reading

Written music encodes two things at once: which pitch and for how long. This topic covers the first half. The second half is rhythm.

A note's pitch is shown by where its head sits on a five-line staff. Higher on the staff means higher in pitch. That is the whole idea — everything else is bookkeeping so that one staff can cover the range of a piano without needing forty lines.

The three things you need

A clef. Five lines on their own mean nothing. The clef at the start fixes one line to one specific pitch, and every other position follows from it. The treble clef wraps around the G line; the bass clef puts two dots around the F line.

Ledger lines. When a note goes above or below the five lines, short lines are drawn just for that note. Middle C sits on one ledger line below the treble staff and one above the bass staff — the same pitch, written two different ways.

Accidentals. A sharp, flat or natural in front of a note shifts it by a semitone for the rest of that bar. These are the difference between C and C♯, and between a piece in C major and one in D major.

Where people get stuck

Almost everyone learns the lines and spaces as mnemonics, then stalls, because a mnemonic is a lookup table and reading music requires recognition. The fix is unglamorous: see the same notes often enough that you stop computing them.

That is exactly the kind of thing a short daily game is good for, and why note reading is one of the five areas Tomus trains.
