I'm playing piano and I have problem going through pieces quickly, I keep pressing wrong keys and it takes me a lot of concentration and practice to get the piece sounding like it should and even after that I still press wrong keys.
I heard studying scales, arpeggios etc and recognising keys and chords immediately would improve my performance but when it comes to theoretical music I'm quite lost and I really don't know what I'm talking about.
What would you suggest? What should I study, or how should I study? Is there any compositions or simply just exercises that can teach me finger independence, different tones, increase the quality of my performance etc. ??
Thank you to everyone who answers, every single one is appreciated. :)
