I'm thinking of guitar to ukulele specifically, though the same goes across the musical spectrum. If I can easily Google uke tabs for aguitar or piano song that exists in Yousician, there's no valid reason why it's not available in Yousician too.

I'm finding myself using Yousician less & less due to the limited catalog for the instrument I'm in. When I discovered deeper catalogues for more popular instruments I was actively disappointed at this clear gap in efficiency. Given rights management has already occured, the cost to onboard more versions of approved songs should be lower, will broaden options for your total user base & if automated is a one time investment that will reap high value repeat yield,
