So I'm looking something up on YouTube the other day and an ad for Yousician plays. I figured they'd have some sort of free trial so why not check it out. This app is wonderful! You install it on your computer and can play through midi with the program. You can learn a number of instruments, I chose piano. It makes it very simple and fun to learn the keys as well as correct finger placement. There is a free and a paid service. The free one (which is what I use) is nice because it gives you an hour each day with interactive instruction. I like that because it keeps everything light and I look forward to my hour of training each day. For anyone looking to learn an instrument, I recommend giving this service a shot. I'm definitely excited to see what all I learn from it. Below is a link to the site if you're interested.
