I guess PianoMarvel fits your criteria but I doubt any tool will remove any of the frustation you're currently feeling. It's just part of learning to play an instrument. > But something about the way piano teachers teach piano doesn't properly click in my brain. Would you be able to articulate what doesn't click with you? Perhaps you need to try other teachers. Not all piano teachers are created equal. There may be a better fit for you somewhere else. > I often mess up but don't realize until I play it for her and she corrects me. This is part of the process. You'll make less mistakes as you get better and your ear develops. Eventually, you'll play a note and notice to yourself "Wait, that doesn't sound quite right". You'll look at the sheet music and sure enough you played a wrong note.
