# Keyboard - Notes

Learn to play notes on a keyboard in four clefs.

### Setup
Clefs Use these checkboxes to select which clefs should be used in the quiz. Notes This popup menu will allow you to select which notes should be displayed: notes on the staff only, notes within 2 ledger lines of the staff, or notes anywhere within 4 ledger lines of the staff. Accidentals Use these radio buttons to select which accidentals should be allowed: no accidentals, single accidentals, or double accidentals. If double is selected, single accidentals are assumed to be allowed as well. Require octave as well as note name Enabling this checkbox will require the user to type a guess of the letter name and the octave (ex. 'C4') rather than clicking on the letter name buttons.

### Learning the Notes
The Keyboard Use the Practice button to see a labeled keyboard and memorize which keys play which notes. Middle C A good point of reference on a multi-octave keyboard is C4, "Middle C." In Aquallegro, C4 is labeled, but on most actual pianos, it is not. Thus, it is often good to be able to recognize C4 by ear.
