Here is an example of what pitches look like when engraved in the theory line:

To enter a pitch, click on the theory-line entry and type the pitch's pitch-class letter name and octave number in the text input box.

Pitch Class

The pitch class is the name of the pitch without its octave designation. It consists of a lower- or upper-case pitch letter C D E F G A B followed by an optional accidental: sharp, flat, natural, double-sharp or double-flat.

pitch letters:	text input:
C	C, c
D	D, d
E	E, e
F	F, f
G	G, g
A	A, a
B	B, b

• To input a pitch letter, type a letter from C, D, E, F, G, A, or B. This is not case sensitive.
• To input a sharp, type the symbol '#' or a lowercase 's'.
• To input a flat, type the lowercase letter 'b' or a lowercase 'f'.
• To input a natural, type a lowercase 'n'.
• To input a double-sharp, type the symbols '##' or the lowercase 'ss'.
• To input a double-flat, type the lowercase letters 'bb' or a lower 'ff'.

Note: While the shortcut keys A, B, C, D, E, F, G for pitch-class letter names are recognized in both upper- and lowercase, flats, sharps, and naturals are case specific and are only recognized as lowercase b , s , or n , respectively. Also note that the letter-name shortcut keys are disabled for pitch and pitch-class identification exercises.

Octave Number

The octave number is the octave in which the pitch belongs. Note that a pitch must have its octave number or else it is not a pitch, but a pitch class. The lowest pitch on the piano is A0 and the highest pitch is C8. Middle-C is C4. Octave 4 begins with Middle-C and includes all the pitches up to the next C, which is the first note of octave 5. Octave 3 is the octave directly below Middle-C, and so on, as shown in this example:

Typing in the Theory Line

To type pitches in a pitch or clef assignment, follow these steps:

1. Click on an entry box for the theory-line editor to pop up just beneath the theory line.

2. Type the pitch (pitch class and octave) as described above into the theory-line editor. As you type, your input will be engraved in the theory line into proper music notation.

3. When you finish typing, press the Enter or Return key or use the Tab key to move to the next entry in the theory line.
