Is there a system of writing scores where people write down the key and the scale degrees instead of black dots?
edit for clarification:
What I mean is that each note in a standard diatonic key has a numeric equivalent (1 for root, 3 for third, etc.). It's hard to read the black dots on the paper based on their approximate location due to my vision, it's near impossible to distinguish notes that are very close to each other. But I would be able to read numbers of similar size--is there a system that utilizes such an approach to representing music where the numbers represent the identity of the notes with respect to their degree in a given key? I have searched and found nothing.
