Introduction. Music-based interventions (MBI) induce emotional states which can modulate memory consolidation. Here we present three experiments studying if listening to music can also modulate memory reconsolidation. Aim. Exp. 1 assessed the effect of arousing and relaxing music during the reconsolidation window. Exp. 2 assessed if an emotionally stronger MBI (i.e., preference music) could maximize its effect. Exp. 3 tested if the results can be explained by state-dependency, re-exposing participants to the same MBI before performing memory tasks. Results. Listening to arousing music reduced retrieval, without affecting recognition over a two-week period (Exp. 1). Such effect was not maximized by preference (Exp. 2). No re-exposition effect was found (Exp. 3). Discussion. Listening to arousing music after reactivating memory can interfere with the re-stabilization process and weaken memory, but it may not be strong enough to eliminate it. This amnesic effect is not explained by state-dependency. In contrast to that observed on memory consolidation, MBI diminishes memory; indicating that MBI interact in a unique way with each memory phase.
