1. Visit 0 (inclusion visit)
* Verification of inclusion and non-inclusion criteria
* Signature of consent
* Information gathering
* Demographic information (date of birth, height, weight, activity, etc.) professional).
* Clinical information about the disease (age of onset and duration of the disease, treatments and their distribution).
* Medical history including present or past medical conditions and any other conditions that may be relevant to the study and their treatment.
* Neurological examination with MDS-UPDRS (Movement Disorder Society - Unified Parkinson's Disease Rating Scale) and NFOG-Q (New Freezing of Gait-Questionnaire) scales
* Explanation and delivery of the agenda for the next 2 weeks
* "Feetme(c)" soles in place
* Remittance of self-questionnaires for a home refill before V1
2. Base Line From the day of inclusion until visit 1 the patient will complete a diary to record the occurrence of falls and freezing, and to self-assess on a visual numerical scale their levels of pain, fatigue and motivation.
3. Visit 1 (week 2)
* Run the 6 minutes test in silence.
* Actualization of the Battery for the Assessment of Auditory Sensorimotor and Timing Abilities (BAASTA).
* Collecting and checking the completeness of the different scales given at visit 0 and helping to fill in incomplete scales.
* Information and training in the use of the BeatPark device (programmed with or without music according to randomization)
* Explanation of the self-education program (number of sessions, duration, location...) for the 4 weeks.
* Delivery of questionnaires to be completed within 3 days prior to the visit 2.
* MRI: morphological sequences (T1 3D, T2 FLAIR, T2\*) and functional sequences (Resting state and with the different types of auditory indication) for the subgroup explored in imaging.
4. Intervention phase
\*Self-reeducation program:
* This program will consist of walking outdoors for 5 sessions of 30 minutes per week for 4 consecutive weeks with the BeatPark device (set to deliver music or not, adapted music or random tempo).
\* Phone call:
* The clinical research associate (CRA) will contact the patient to ensure the proper functioning and compliance with the rehabilitation program, if any difficulties are encountered.
\*Self-assessment schedule:
* From the day of visit 1 through visit 2 the participant will complete a diary to record the occurrence of falls and freezing, and to self-assess on a visual numerical scale their levels of pain, fatigue, motivation and satisfaction.
5. Visit 2 (end-of-study visit, week 4):
* Neurological evaluation with the MDS-UPDRS, NFOG and CGI (Clinical Global Impression) scales.
* Running the 6 minutes test in silence
* Achievement of the BAASTA
* Collection and verification of the completeness of the different scales submitted to V1 (and completed within the last 3 days) and helps to fill in incomplete scales
* Checking for no change in anti-parkinsonian treatment.
* Return the equipment to the investigation team.
* MRI: morphological sequences (T1 3D, T2 FLAIR, T2\*) and functional sequences (Resting, T2 FLAIR, T2\*). state and with the different types of auditory indication))) for the subgroup explored in imagery.
