This instructable is intended to teach you to do just that. In the next few steps I'm going to teach you to play music meant for guitar on a piano using basic music knowledge and some simple math.
This is my first instructable, and I got a little lazy with picture, I'll add more later.
Step 1: Things You'll Need.
A six string guitar (acoustic or electric, doesn't matter).
A Piano or electric keyboard.
a guitar tab.
Basic music knowledge. ( if you don't have this, don't worry, I'll tell you what you need to know)
Basic guitar skills. ( Not teaching it)
Basic piano skills. ( Not teaching it)
basic math skills, adding subtracting.
Step 2: Finding the First Notes.
Read the tab and make sure your guitar is in the right tune for what ever tab you are using. you can find a good online tuner here. I'm going use I constantly thank god for Esteban by Panic! At The Disco, this song is tuned in drop D, or DADGBE.
Now look at the first numbers on the guitar, hopefully you know these stand for what fret to press your finger down on and the bottom line is the thickest string, the first notes for the song I'm playing are 5, 3, 6, 4, 3, 3 on strings D2 (second d string), G, B, B, G, B.
Step 3: Converting the The First Notes to Piano
Music notes go from A A# B B# C C# D D# E F F# G G#, keep in mind there is no E#. The tuning of the guitar is the notes the strings make when you just strum it with out your fingers on the fret board. so in the tab I'm using, the first note is F#, I found this out simply by counting the frets until I reached the fifth fret starting from D then going to the first fret, which is D#, then the next two frets, which are E and F, than the next two frets, which are F# and G, G is the fifth fret.
Continue to do this with each note for the tab I'm using and you will get G, A#, E, D, A#, C#. Now that is all the note converting you need to do, move on to the next step.
Step 4: Converting the Rest of the Song
Read the tab and play the notes we found on the piano. after that the next frets would be 4, 3, 4, 3, 3, 3, same configuration as the last notes. subtract the difference between 5 and 4 from G on the piano keys and you should get F#. do the same with all the others and you should get F#, A#, D, C#, D, C#.
