I'm 23 years old. I'm planning on buying a digital piano and learn to play on it. I know nothing about music, I'm never had any lessons on it. Is it even possible for me to learn to play on it without a teacher, just via internet? After buying a digital piano, where do I start and how do I progress. Once I learn how to play on a digital piano, will I be able to play on a real one?
Sure. https://yousician.com. And it seems they have a 50% discount for new subscribers and a 30 day trial. I use it and it's certainly for beginners and certainly worth the small fee.
I've learned from the guitar, bass, singing and now I just bought a piano. I wish they had drumming but how many people have a midi drum set. (But it could be with just one midi pad solely to practice rhythms.)
What I like is that they have both tab and staff (real music) ... I think it's not that hard to learn to read the staff and that TAB is too much of a crutch.
You say "digital piano" ... does that mean MIDI or just that it has its own sounds and some digital display?
If you need a MIDI keyboard look at IK Multimedia iRig Keys Pro full-sized 37-key MIDI controller. Over the weekend they were 50% off ... maybe one will still give you one for $75 ... I see they're still $99 on Amazon.
