Many blind people may want to learn music. However, we cannot do this via researching pictures nor see what to do from videos. If you search for the right things on the internet, you can learn your instrument well without sight.
The best place I have found for this is Youtube. Start by searching for how to do guitar chords. This will give you detailed videos on where you should place your fingers and how all this is done.
Once you’ve memorized chords, you can search for songs. This is done with a similar process akin to the one above. Search for “How to play” with a song title on your instrument of choice. You will then get tons of results for that search.
Once you’ve searched, you may then click on any video and they will walk you through it all. You may choose to take notes or just learn off of memory. Over time, you will become a gret musician.
