Sight Singing Game
Imagine & sing sounds
Sight-singing games invert the melodic games. Instead of hearing something and not seeing how to play it, you see how to play something but don't hear it. Rather than finding the sounds on your instrument, you imagine and sing them — this is audiation.
This connects the rich sensation and coordination of your voice to your ear. It may take some initial pitch-matching practice (singing back the sounds you hear), but that is a hugely valuable skill in its own right and can start your singing journey.
