You can use the right mouse button to flip the items in the opposite order or the item chooser to directly pick an item. Press and hold a mouse button or on the touch screen to automatically choose the last item selected on a column. Double click or tap on a previously selected item in your guess history to mark it as 'correct'. Such marked items are automatically selected in your current and future guesses until you un-mark them, again by double clicking or tapping.

Levels 1-5 will offer treble clef to practice and levels 6-10 will offer bass clef.

Odd levels display a vertical playing line when you click the drum, which helps you see when to click, to follow the rhythm. Click on the drum when the line is in the middle of the notes.

Even levels are harder, because there is no vertical playing line. You must read the rhythm, and click it back in tempo. Click the metronome to hear the quarter note tempos.

Click on the reload button to replay the rhythm.
