AGO AGO Accompaniment & Collaborative Skills 2 — Questions and Answers
Question 1: When accompanying a funeral service soloist performing 'Ave Maria,' which registration principle applies?
- Use the brightest mixture stops available
- Select warm, soft stops (strings or flutes at 8') that support without drawing attention (Correct answer)
- Employ full swell box closed throughout
- Always use only the Great division
Correct answer: Select warm, soft stops (strings or flutes at 8') that support without drawing attention
Funeral accompaniment calls for warm, subdued registration that comforts mourners and supports the soloist without becoming the focus.
Question 2: In collaborative organ playing, what is the purpose of a conductor's 'preparatory beat'?
- It signals the organist to stop playing
- It establishes the tempo, dynamic, and character before the ensemble begins (Correct answer)
- It tells the organist to increase volume
- It indicates a key change is coming
Correct answer: It establishes the tempo, dynamic, and character before the ensemble begins
The preparatory beat communicates tempo, character, and dynamic level to the ensemble (including the organist) immediately before the music begins.
Question 3: When sight-reading an accompaniment that has a sudden key change, the best immediate response is to:
- Stop playing and start again from the beginning
- Acknowledge the new key signature mentally and continue without interruption (Correct answer)
- Transpose everything back to the original key
- Skip the passage entirely
Correct answer: Acknowledge the new key signature mentally and continue without interruption
A skilled accompanist mentally absorbs the new key signature and continues playing, maintaining the ensemble's momentum even if the transition is momentarily imperfect.
Question 4: Which skill does the AGO Colleague (CAGO) level exam test under 'keyboard skills' related to accompaniment?
- Memorizing six concertos
- Playing from a figured bass or lead sheet in a hymnal style (Correct answer)
- Conducting a full orchestra
- Tuning the organ manually
Correct answer: Playing from a figured bass or lead sheet in a hymnal style
The CAGO exam tests practical keyboard skills including playing hymn accompaniments and working from figured bass, demonstrating harmonic understanding in a practical context.
Question 5: An organist accompanying a Baroque violin sonata should primarily reference which source for ornamentation guidance?
- Modern jazz improvisation charts
- Period treatises such as C.P.E. Bach's 'Essay on the True Art of Playing Keyboard Instruments' (Correct answer)
- 20th-century orchestration manuals
- Contemporary pop music notation guides
Correct answer: Period treatises such as C.P.E. Bach's 'Essay on the True Art of Playing Keyboard Instruments'
Period treatises like C.P.E. Bach's Essay provide authoritative guidance on Baroque ornamentation, articulation, and keyboard style appropriate for historical performance practice.
Question 6: When an anthem accompaniment has a vocal score only (no separate organ part), the organist should:
- Refuse to play until a dedicated organ part is provided
- Reduce the SATB choral score at sight, choosing appropriate registration (Correct answer)
- Only play the soprano line
- Transpose to a more convenient key
Correct answer: Reduce the SATB choral score at sight, choosing appropriate registration
Reducing a choral score at sight — playing the essential voices and bass line — is a required skill for church organists working without dedicated organ parts.
