Learn to read the alto clef, the C clef on the 3rd line and the standard clef of the viola. A note appears and you name it. The quiz has 10 questions and gives you a score at the end.
Tip: Middle C is the middle line, and every other note is counted from it. From the bottom, the lines are F A C E G and the spaces are G B D F. If you play the viola, this should feel familiar.
How the alto clef works
In the alto clef the two curves meet on the middle line, which makes it middle C (C4). The staff is centered on middle C, with two lines below and two above, so it is symmetrical: from F3 on the bottom line to G4 on the top line. That is why it suits the middle register of the viola so well.
Who reads the alto clef?
The viola uses it as its main clef and switches to treble clef for very high passages. The alto trombone also reads it, and alto voices used it in older choral scores.
To review the theory behind this clef, see the alto clef guide in the dictionary. The online metronome is handy for practicing sight-reading in time.
