Note Carpet 4‏+

The Note Carpet is an innovative music theory teaching aid.
You can use it to illustrate tonal relationships and discuss musical issues.

* Move notes to set a key and modulate.
* Recognize the scale's own notes.
* Play notes and chords with a simple sound.
* Recognize enharmonically interchangeable notes.
* Understand the relationships between notation, fifth relationships, keys, degrees.

The Note Carpet consists of an immobile checkerboard-like grid with a highlighted center and a pattern of note names that can be moved against it. By shifting notes into the center you get:
* The scale degrees of the notes, colored and numbered left and right.
* The root, the red note in the center.
* The mode, which you can recognize by the solmization syllable of the root (below and above). Do is major. La is minor.
* The key (root and mode).
* The scale and its accidentals (right).
* The range of in-scale notes (white) and out-of-scale notes (black).
* Aspects of musical notation: white notes can be written without accidentals, black notes must be written with accidentals at least once per bar.

For a better understanding, common features of the notes are also displayed:
* At the left, the root note of all notes in the line, i.e. without alteration. The sequence corresponds to the staff lines and spaces.
* At the bottom, the note name without octave number. The sequence corresponds to the fifth relationships of the notes.

At the bottom right is a number that encodes the projection of the key onto the mode circle of fifths.
If you install the "Mode Cirkel" app or the "MIDI Solfa Mode-Go-Round" app, a button is displayed here that sends the current key to the corresponding app.
There you can study further aspects of music theory.
