(Section: 3 / Part: II / Paragraph: f / Sub-Paragraph: ii)

A: 3.Part II.f.ii should read: "Participants will play one pitch at a time, holding it for a duration of 5 seconds as indicated by signals from the event supervisor. For devices with a quick decay time, multiple attacks on the pitch are allowed (for example, striking a bar multiple times with a mallet or plucking a string). The pitch measurement will be the average value during the 5 seconds. Participants will wait until the supervisor records the measured pitch frequency and indicates that they may proceed before playing the next note in the sequence."; ("average" replaced "best".)
