    SimplePiano 1.106 is an aid for the beginner who's learning to play piano and read music.
    It uses Maestro fonts (that are installed with the program) to show the notes played on the treble and bass clef staffs.
    The notes played are also highlighted on a 60-key on-screen piano keyboard.
    You can play it using the keyboard, the mouse, or a midi keyboard connected to the computer (I recommend the M-Audio Keystation 61es).
    The Circle of Fifths can be displayed, and when a key in it is selected, that key's signature is shown on the staffs.
    Any of the eight most-used chords can be selected and played by playing the chord's root key. Chord inversions can also be selected.
    A random note reading exercise is included.
    The midi instrument (128 choices) and output sound (Windows or soundcard sound) are selectable.

    SimplePercussion 1.063 has 47 percussion instruments that can play together in a loop of up to 70 beats (depending on your screen resolution).
    Just mark the boxes corresponding to the instrument(s) and the beat, and then play it. A moving vertical line shows the beat being played.
    Save to a file, open a file, change beats/second, beats/loop, and beats/heavy vertical accent lines.
    Also works nicely as a simple metronome.
