NACCM CMC common mistakes
NACCM CMC · Understand the traps and how to avoid them.
Choosing repertoire on personal taste or emotional appeal alone, without checking that the text and ritual function match the specific moment of the liturgy (e.g., using a general Marian hymn during the Communion procession).
Candidates often prepare music as a set of favorite pieces rather than as ministers of a rite, so they never map each item to the liturgical action it accompanies.
What to do instead
Build a planning grid: for each Mass part (entrance, Gloria, responsorial psalm, acclamation, preparation, Sanctus, Memorial Acclamation, Great Amen, Lamb of God, Communion, sending), list the required ritual function and the text criteria before selecting titles. Justify every selection in one sentence tied to the rite.
Treating the responsorial psalm as a solo performance piece and replacing the prescribed refrain with an arbitrary song.
Candidates confuse the psalm with the other processional songs and forget that the refrain must be the Church's response to the first reading, sung by the assembly.
What to do instead
Memorize the structure: cantor/lector at the ambo, psalm tone or setting that preserves the biblical text, refrain simple enough for the assembly to repeat after one hearing. Practice leading the refrain so the assembly can join without printed music.
Misidentifying the modes or confusing modal and tonal function when analyzing a chant or hymn melody.
Candidates learn mode names as labels (Dorian, Phrygian, etc.) without practicing final, reciting tone, and ambitus on real melodies, so they guess from the first note.
What to do instead
Drill the analytical method: locate the final, then the reciting/tenor pitch, then the ambitus, then the characteristic cadence formulas. Analyze at least twenty chants across all eight modes and write the final and tenor for each before naming the mode.
Setting choral or congregational music in keys or ranges that exceed what the assembly or ensemble can actually sing, then blaming the singers for weak participation.
Candidates transpose by feel or by instrumental convenience rather than by vocal range and tessitura, and they do not test the piece with the actual forces.
What to do instead
Before rehearsal, determine the practical range of each voice part and the assembly's comfortable range (roughly a ninth to a tenth around middle C for mixed congregations). Transpose to keep the melody within that band, and rehearse the final key with the real ensemble and a sample of the assembly.
Describing the Church's musical tradition only in vague terms ("chant is ancient and beautiful") without accurate historical or documentary specifics.
Candidates rely on general impressions from parish experience instead of the actual documents and historical development, so they cannot answer questions that require precise attribution.
What to do instead
Build a dated outline of the tradition: chant sources and their development, the role of the pipe organ and other instruments, the reforms tied to the liturgical movement and the Second Vatican Council, and the key magisterial and curial documents on sacred music. For each entry, note one specific provision or principle and be able to state it accurately.
Assuming that because a style is popular or contemporary it is automatically suitable for liturgy, or conversely rejecting all contemporary music outright.
Candidates reduce the question to style preference and never apply the criteria of liturgical fitness, textual integrity, and the active participation of the assembly.
What to do instead
Apply a consistent three-part test to any piece: does the text express the faith of the Church and fit the rite, is the music technically and aesthetically worthy, and does it enable the assembly's participation. Write a short rationale for one traditional and one contemporary selection using the same criteria.
Directing rehearsal by stopping and restarting the whole ensemble repeatedly instead of isolating the specific problem passage.
Candidates imitate how they were taught or want to appear thorough, but full restarts waste rehearsal time and teach the ensemble to expect failure at the same spot.
What to do instead
Rehearse in segments: identify the precise measure and voice, slow it down, fix the pitch or rhythm in isolation, then reintegrate in context. Keep a written rehearsal plan with time allocations and a list of three priority goals per rehearsal.
Giving directions as vague praise or criticism ("that was nice, let's do it again") rather than specific, actionable musical instruction.
Candidates lack a vocabulary for diagnosing ensemble problems and fear being perceived as harsh, so they default to encouragement without correction.
What to do instead
Practice the diagnose-instruct-model-verify sequence: name the issue (e.g., "altos are flat on the third phrase"), give a concrete instruction (support the breath, raise the soft palate), model or have a section leader model it, then verify. Record one rehearsal and count how many instructions were specific.
Working without the required permissions, licensing, or reprint approvals for copyrighted music used in worship or reproduced for the assembly.
Candidates assume parish use exempts them from copyright obligations or that the publisher's pew edition covers all uses, and they do not know which rights must be cleared.
What to do instead
Establish a checklist: confirm the source and copyright status of every text and tune, secure reprint or projection permissions through the appropriate licensing route, keep records of what was used and when, and confirm the terms for any recording or streaming. Review the checklist before each season's planning.
Treating continuing education as optional or as accumulating attendance at workshops without documenting or applying what was learned.
Candidates are busy with weekly demands and view formation as a personal extra rather than a professional obligation tied to ministry competence.
What to do instead
Set an annual formation plan with specific goals (e.g., chant repertoire, conducting technique, liturgical document study), log each activity with a short reflection on how it changed practice, and review the plan quarterly with a mentor or supervisor.
