How hard is it to learn guitar, also, I played piano when I was younger but don't play anymore, will that help

Answer 1

Any sort of musical background will help. What sort of style do u want to play? Basic folk guitar- - chords and strumming, is fairly easy, given 3 things. 1) a realisation that ur fingers are going to hurt from pushing the strings down. 2) u need plenty of practice.3) u have a reasonable sense of rhythm.
When u buy a guitar, go to ur local music shop and check out what's in ur price range. go for acoustic to start with. Steel strings wil sound brighter, nylon strings will be easier on the fingers at first. Take a knowlegeable friend if possible, or get the assistant to play for u. Hold one, see how it feels. Try pushing a string down and see if u can make a note easily. U should also buy a tuner and a chord book.
Choose 2 or 3 chords - A D E are good. Practise playing one at a time, then change between them. There are stacks of songs out there that use these chords - early Chuck Berry (Johnny B Goode). Children's songs- "He' got the Whole World In His Hands" (D A.). All the best, and Happy Picking. Hope this helps.
