That is something about chord progression, not chord construction. Chord progression meaning when you hear a song you can be able to catch hold of what type of chord the song is playing.
Yup, to catch the chord of a song, you basically need intutitive idea to create chord that suits the music piece. Basically, it is best to sing along the music and touch the fretboard to play along. If you feel that the chord does not suit, try another chord. I have explained about chord progression during my first post. Every time you listen to a song, you must first catch hold of what is the root note it is playing.
After you find the root note or key, then other chords that follow is easy. What is root note and how to find root note? Root note is the base of the song that other chord will follow with the chord progression sequence. Eg. I have explained earlier, C root key is C-Dm-Em-F-G-Am-Bb. How to find the root key? When you start singing, find the base of the song. For example, when you play "Eric clapton-Tears in heaven". when Eric Clapton start singing, hum the first tune, and then go catch hold of what base it is in the fretboard, and you slowly will know the root key of this song is A.
After finding the root key, the rest of the chords will be quite easy, if you understand the chord progression. If you learn chord progression it is easy to find the other chords, rather than spend the whole time catching all the chords of a song.
