Note Carpet vs Learn Rexx Programming Offline

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.
