Bells 1 and 3 were rather easy, but I am not too sure that I have the right answer for Bell 2. Is it (answer deleted)? 1 is obviously (answer deleted), and 3 is (answer deleted), correct?

You have the right answers for the three of them but you will notice that we have deleted the answers so as not to spoil the fun for the others. It seems you have not reached Bells 4 and 5 yet, in the Non-Chordal Tones section. By the way, did you spot anything unusual in Bell 3?
