Below are links to videos with play-throughs of common AMEB pieces. Each link has a playlist with usually 3 different speeds. The fastest speed is the correct speed for the piece. Only try to play along with the fastest speed once you’ve mastered playing along at the slower speeds.
The videos linked below cover a wide range of topics for improving your playing. These tone and technique exercises look at different ways of improving the sound production and accuracy of intermediate players. Each tutorial also has a PDF with all of the exercises and explanation written out.
