Let be an algebraically closed field. Let be a local commutative finite dimensional -algebra and let be a quiver with no loops or oriented cycles. We show that mutation of -exceptional sequences over in the sense of Buan, Hanson, and Marsh coincides with the classical mutation of exceptional sequences defined by Crawley-Boevey and Ringel. In particular, the braid group acts transitively on the set of complete -exceptional sequences in .
