The goal of this clinical trial is to study the feasibility of a 6-week piano playing training intervention in a subacute stroke population. More specifically, the investigators aim to (1) implement and test the feasibility of the intervention in the subacute stroke rehabilitation program; and (2) explore the acceptability of the supervised training sessions and home practice sessions. Researchers will also (3) estimate and contrast the effects of the piano training intervention as compared to conventional therapy on manual dexterity, coordination, functional use of the upper extremity, attention and mood. Therapy specifically provided as part of this project will be delivered above and beyond usual therapy time in both intervention groups. Participants of the piano group will: * Engage in a step-by-step musical training consisting of two supervised, individual 45-min sessions per week for 6 consecutive weeks, for a total of 12 sessions. * The supervised session will also be complemented with a biweekly home program (15 minutes) consisting of piano exercises. Participants in the conventional group will: * Engage in two individual 45-min sessions per week for 6 consecutive weeks consisting in conventional occupational therapy treatment. * They will also receive a biweekly home program consisting in occupational therapy exercises (15 minutes).
