== How to read the scores == | |||
The octave is divided into 41 equal steps, a tuning called 41-ET or 41edo or 41-equal. Whereas 12-equal has 100¢ steps, 41-equal has steps of 29.27¢. We can round this off to 30¢ for convenience, since a cent or two doesn't matter much in practice. This 30¢ interval is called an arrow, because the little arrows by the noteheads raise or lower the pitch by 30¢. Notes are called up-E, down-F-sharp, etc., written ^E and vF#. A note that has no ups or downs is called plain. The 7 plain natural notes are close to 12-equal, but they do deviate slightly. The pattern is easy to see if we arrange the notes in chain-of-5ths order: | |||

|} | |||
All the notes with sharps are extra-sharp. All the notes with flats are extra-flat. Note that G# is sharper than Ab by one arrow. Thus G# is also ^Ab, and Ab is also vG#. (Likewise C# = ^Db, vD# = Eb, etc.) Since G# ≠ Ab, the familiar circle of 12 fifths opens up into a spiral. Because this spiral is really a circle of 41 fifths, the innermost and outermost few notes overlap. | |||

In the table, D is the "anchor note" that agrees with standard tuning exactly. D is an ideal anchor because it makes the table symmetrical. But F, C, G and A have all been used by microtonalists historically. If hired to record a part remotely, always ask what the anchor note is! | |||
Assuming D is the anchor note, let's find some pitches. ^D is 30¢ sharp and vD is 30¢ flat. F# is +10¢, so vF# is -20¢. C is -5¢, so vC is -35¢. In certain situations, double arrows are needed. ^^C is called dup-C and vvC# is dud-C-sharp. Note that ^^C = vvC#. One more equivalence: ^^C = vDb. Thus 3 arrows = a minor 2nd. These equivalences are useful, because if you've already found vDb on your instrument, and you see ^^C on the score, you know what to do. | |||
* one arrow = half a fret = a quarter-sharp or quarter-flat | |||
* two arrows = one fret = half a sharp/flat | |||
* three arrows = 1.5 frets = a minor 2nd | |||
* four arrows = two frets = one sharp/flat = an augmented unison | |||

So how exactly would a vocalist or violinist or trombonist tune a precise number of cents sharp or flat? It helps to borrow a Kite guitar and familiarize oneself with the sound of the various intervals. It also helps to understand just intonation. See the "What it is -- long explanation" page for an overview. In practice, use the ups and downs as a rough guide, then listen to the other parts and try to blend. For example, the downmajor 3rd from D to vF# is 380¢, very close to the just 5/4 of 386¢. So one simply flattens the F# until the interference beats go away. But wait, should the 3rd be 380¢ or 386¢? In general, deviating slightly from 41-equal is fine, if it makes the chord smoother. | |||
