This paper describes solutions to improve the access to music for blind people. These solutions are proposed during the European project Music4VIP. The objective of the project is to help teacher to teach music to blind pupils and to create tools which will enable blind people to learn music independently. A method base on SUS questionnaire is described and used to have a quick feedback for users. These first results indicate that users perceive our solution as good but these results have to be consolidated with further surveys with a large number of respondents.
