Do I need to be experienced? – Yes. The service is best for someone who can play at least basic songs. The more experienced the better.
Can I use a Keyboard? – Yes, a keyboard or a piano is fine.
Will I be an expert player after a session? – No, it takes longer than that. You will understand your problem and why you are having problems. You will also have a practice schedule to follow to overcome the problem.
Will I need more than one session? – You shouldn’t need any more sessions for a problem. Providing you follow the instructions provided to overcome the problem and practice, your problem should be overcome. You can of course come back for any future problems that may occur with your playing.
Do you guarantee results? – I would love to but your success depends on you. How closely follow the instructions, how often you exercise or practice, your innate ability. There are ultimate reasons why you don’t succeed. There is no reason why you should not.
An exercise for you. Find a new song and try to play it. Record your playing. Leave the song alone for seven days. Record and play the song and compare the two recordings. Now find another song and record your first playing it. Then practice it for 10 minutes every day. After seven days record your playing and compare the two recordings.
