Abstract
We examined collective efficacy beliefs, including
levels of within
-
group agreement and
correlation with performance quality, of instrumental chamber ensembles (70 musicians,
representing 18 ensembles). Participants were drawn from collegiate programs and intensive
summer music festivals located in the No
rthwestern and Western regions of the United States.
Individuals completed a 5
-
item survey gauging confidence in their group’s performance abilities;
each ensemble’s aggregated results represented its collective efficacy score. Ensembles provided
a video
-
r
ecorded performance excerpt that was rated by a panel of four string specialists.
Analyses revealed moderately strong levels of collective efficacy belief and uniformly
high within
-
group agreement. There was a significant, moderately strong correlation bet
ween
collective efficacy belief and within
-
group agreement (
r
S
= .67,
p
< .01). We found no
relationship between collective efficacy belief and performance quality across the total sample,
but those factors correlated significantly for festival
-
based ensem
bles (
r
S
= .82,
p
< .05).
Reliability estimates suggest that our collective efficacy survey may be suitable for use with
string chamber ensembles. Correlational findings provide partial support for the theorized link
between efficacy belief and performance
quality in chamber music settings, suggesting the
importance for music educators to ensure that positive efficacy beliefs become well founded
through quality instruction.
