bending

[iommi]

Someone please reply to this,I tried posting this a several times.Suppose i have to bend 10b12 ,Can someone define what pitch means?I try bending but don't know how much to push.As a result if the bending is on the 2nd string i try pushing the 2nd string,3rd,4th.SOmeone please help

10b 12 this is a string freted at the 10th and a bend used so that fret now sounds like the 12th instead of the 10th
best way is to actually play the 12th fret and get what it soundslike in your head now play the 10th fret and bend the string until it sounds like the 12th fret
is this making sense? i am finding it hard to put into words what im trying to say
Hope this helps

If you were to do a hammer-on(10h12), it would sound similar to 10b12. You just bend whatever string that should be bent, fretted at 10th, to match the pitch of the same string fretted at the 12th.

To get an idea of the amount of bend here's a often used technique in blues and rock that will allow your ear to develop as well. Remember it's easier to do bends in the middle of the fretboard so:

What we're going to do is a 12b14 on string 2.

First play 14 on 2. Now play 9 on 1. Same note right? Now you can use this knowledge to give yourself a reference point. (It also happens to sound great.)

Put finger 4 (baby) on fret 12 of string 2. Remember when bending you don't have to use just one finger for the bend so support the bend by pushing also with fingers 2 and 3 on string 2 below finger 4. Put finger 1 on string 1 at 9. Do not bend string 1. Now play both strings 1 and 2 at the same time and bend string 2. You'll hear when the tones match.

Many guitarists slide the bending not and fingers under the next string (in this case string 3). This tends to work best since if you push 3 as well your much more likely to sound that string. Under is better.

Lighter strings are easier to do this with until you're used to it but heavier strings sound better and are easier to control. If you're using an accoustic, use light strings with the G (3 string) an unwound string. You will likely have to buy a 20 seperately as most accoustic strings come with a wound G.

bending is simpler than it can be made out as. all of the stuff others have suggested is worth doing, like checking the tone against the one produced by hammering the higher note. but in the end once you get better from practising, it'll just start to sound right to the ear. the boring but best answer is the same as it is most of the time: just practise.
