Wide, Narrow, & Pure Intervals

Wide, Narrow, & Pure Intervals

When tuning pianos, we are often required to produce wide, narrow, or pure intervals. Wide and narrow intervals beat because they are not pure. The farther from pure they are, the faster they beat. See how good you are at analyzing the relationships between wide, narrow and pure intervals, relative beat speeds, and the relative frequencies of these interval notes. You have 20 minutes to complete the quiz. You need 100% to pass. Good luck. (I finished it in about 10 minutes, but got two wrong!)
