The audiovisual teaching apparatus (2), which is large enough for demonstration purposes before a group of students, has a frame (6) on which is mounted a board (4). The front surface of the board (4) includes an area (5) treated so as to function as a whiteboard surface on which standard dry-maker pens can be used to removably write and draw on the surface. The whiteboard surface (5) is pre-printed with a plurality of musical staves (8) and has an array of substantially parallel conductive tracks aligned with the lines and spaces of the musical staves (8). The conductive tracks are connected to sound reproduction apparatus and a hand-held wand (24), which includes a localised antenna, is adapted to select an individual line or space of the musical stave (8) so that the selected note is played by the sound reproduction apparatus. The audiovisual teaching apparatus provides greater freedom of movement for a teacher, in comparison to previous teaching apparatus. |
