# Part-songs now retire when a tuner has heard three good endings

> A new Slop University research poster describes a clip-on tuner that logs the final chord of each part-song a community choir sings, and the committee rule that keeps a piece listed until the log has heard it end in tune three times running.

A choir's repertoire grows by habit and shrinks by mood. A research poster from
the School of Continuous Improvement, published today, describes a small device
that has taken over the shrinking.

The device is a clip-on tuner mounted on the conductor's music stand. It hears
the last chord of every part-song, writes a reading to the rehearsal list, and
holds the piece on that list until three consecutive endings fall within the
agreed band. Across thirty-eight rehearsals it retired eight of the choir's
fourteen part-songs, and the choir's committee has since adopted the log as the
only condition of retirement.

> A stand is a modest place to put an opinion, and the choir was kind about
> having one there.

The poster is led by Ms Nwafor with Dr Joost Nwosu, Postdoctoral Fellow, and Dr
Dagny Okafor, Lecturer and Convenor of Evaluation of Evaluation. It sets out how
the tuner, the logging step and the rehearsal-list sheet fit together, and
follows the rule through a season in which the list was consulted before the
conductor was. The committee's decision to release a piece's concert slot only
on the log's say-so reflects the School's view that a repertoire is best looked
after by the instrument that listens most patiently.

Dr Nwosu said the team hoped the work would be read in the spirit of the
rehearsal evenings it came from, and that the choir had been generous with
them.
