CROSSOVER DESIGN After the stroke patients have finished their upper limb rehabilitation with CCS and are no longer receiving any physiotherapy or occupational therapy to improve it, this study aims to establish if their upper limb function is maintained, deteriorates, or improves. In order to do this the investigators will have a waiting list group who wait 9 weeks after the end of their CCS rehabilitation but are assessed at the same time points after their baseline measure as the treatment group. This enables us to compare the results of the treatment group with the waiting list group, in other words 'treatment compared to no treatment after CCS rehab has ended', and establish if the music therapy has been effective. The investigators can also compare the results of both groups and determine if the participants who received music therapy earlier performed any differently than the waiting list group.
