  1. What is 'tracker action' in a pipe organ?

    Answer: A mechanical linkage of wooden strips directly connecting keys to pipe valves

    Tracker action uses direct mechanical connections (trackers) between the key and the pipe valve, giving the player tactile feedback.

  2. In the AGO graded examination system, the Colleague (CAGO) level requires:

    Answer: Performance, written theory, and keyboard harmony skills at a basic service-playing level

    The CAGO is the entry-level AGO credential encompassing basic performance, hymn playing, and keyboard harmony competencies for service playing.

  3. The 'Tierce' stop (1⅗') reinforces which partial of the harmonic series?

    Answer: 5th partial (seventeenth)

    The Tierce at 1⅗' sounds a seventeenth (two octaves plus a major third) above written pitch, corresponding to the 5th harmonic partial.

  4. What is the recommended approach for managing page turns during an organ recital performance?

    Answer: Use a page-turner, photocopy problem pages, or use a tablet with a page-turn pedal

    Organists typically employ page-turners, rearranged copies, or digital tablets with foot-operated page-turn pedals to handle turns without interrupting performance.

  5. Which stops form the 'principal chorus' that is the tonal foundation of a classical organ?

    Answer: Principal 8', Octave 4', Super Octave 2', and Mixture

    The principal chorus consists of graduated open flue pipes (8', 4', 2') plus a Mixture that reinforces upper harmonics, forming the organ's classic bright sound.

  6. When transposing a hymn accompaniment on the organ during an AGO exam, the candidate must:

    Answer: Transpose all parts including the pedal simultaneously at sight

    AGO transposition requirements expect complete four-part plus pedal transposition, demonstrating comprehensive keyboard harmony facility.

  7. A 'Mixture' stop in organ registration serves to:

    Answer: Add upper harmonics that reinforce the fundamental and brighten the overall sound

    Mixture stops contain multiple ranks sounding harmonics 2, 3, 5, and/or higher, which add brilliance and presence to the principal chorus.
