How to find out tabs or lead of songs??

First, you must understand that it's not at all difficult. It's a bit like riding a bicycle. You have to do it to know how to do it. And just like riding a bicycle -

1. Tabbing is easier than it seems
2. It just needs a bit of practice
3. It takes some time to learn
4. Tabbing is hard at first and gets easier as you progress
5. Once you learn how to tab a song by ear, you can't forget it
6. It's faster, if you have someone teach you how to
7. You enjoy the result in both cases

Prerequisites:

1. You must know the song well ( must have heard it a couple of times)
2. You must know how to write in tab notation
3. You must be patient

What this tutorial teaches you:

1. How to find the scale / key of a song
2. How to find the tabs of a song on a guitar
3. How to find the scale of a song on a guitar

So, here's the process of tabbing a song by ear:

1. Think of it as singing the song with your hands on the guitar.
2. First listen to the song - this will get your mind to catch the original scale of the song.
3. Try humming the song - this will make you sing the notes of the song
4. Now catch a few notes of the song by trying to play it on the guitar. It's a trial and error process.
5. Now, when the pitch goes up, play a higher note to match. Play a lower note when the pitch goes down. Match and play with the humming.
6. Play again and again from your mind try to remember the sequence.
7. As more and more of the song unfolds, the easier it will get to figure out the rest.
8. Add details and things like hammer ons, pull offs, etc on subsequent passes
