How to play by ear?

I was reading through the local music forum and I see this post by one of the people, asking for tips on how we play by ear. I read through it and I think that the replies given are very useful. I thought it would be nice if I can share with the rest here as well. I've been through this before and had difficulties in trying to transcribe a song. It took a while for me to actually manage to transcribe my 1st song (I remember the song was Haunted).

Anyway, here's the link to read all the replies:

OR, you can just read this. I think this guy really explains almost all the crucial thing. 

1. Figure out the key of the song by finding the root chord. This is the chord that every other chord in the song will feel like changing to eventually. Very quickly breeze through all possible root position major chords to find one that "sits" with the song. Pop songs are easy because the root chord is normally very strong, in fact, for this song it's the first chord. And to make it easier, they hum the triad of the chord for you (0:00-0:04). This song is in Eb.

2. Know what are the "normal" chords in that particular key (in music lingo, you're looking for chords diatonic to the key). For brevity, I'll just mention that there are 7 diatonic chords in every key, numerically notated in Roman numerals: the Root or I chord, minor ii, minor iii, IV, V, minor vi, half-diminished vii, back to I. Pop songs don't want to scare listeners with weird chord progressions, so they tend to be easy and stick to every possible permutation of I, IV, V, minor vi. In the case of the song, it's Eb, Ab, Bb, Cm.

3. Find the intervals of the chord changes. Long story short, when Eb changes to Ab, there's a certain "sound" to that space between the two chords. That space will sound different between Eb to Bb, Ab to Bb, Cm to Bb, etc. At first, I can assure you the process is quite laborious; I fondly remember having scrapbooks of notes I took while figuring out chords to a song. Since a guitarist can only really play one chord at a time, it's a process of elimination to find out what the next chord is (assuming you've done Step 2). In time, you'll be able to hear I-IV, I-V movements, then extend that over longer chord changes, like I-IV-vi-V.

4. Then figure out how long each chord lasts (ie does the chord last for one measure, does it play over two? Is there half/double time chord changes?) according to the time signature. Neon Trees isn't Dream Theater, so it's strictly 4/4 for the entire song.

In order to do things like playing by ear and improvise, we do need some knowledge in music theory. There are many guitarists out there who play guitar by relying a lot on Guitar Pros and tabs. I am not saying that they are not helpful resources. You may be able to play a tough song through reading tabs and GP and from that you will definitely gain some skills. But I believe that skill and music knowledge must increase at the same pace. Without any knowledge in music theory, you might find yourself only covering songs that already exist and never try to write your own. In conclusion, when we play guitar, we can't neglect the theory part as it is needed in order for us to go to the next level in our guitar-ing.
