CH-002 • Dominant 7th Open Chords

Questions...

[JC]

In the Dom 7th chord lesson it says You should mute the 6th string (B7- and C7-chords). I was just wondering about the reason for this. Why not just avoid playing that string? (as is usually recommended) Am I missing something that's pretty obvious, maybe...?

cheers

I had one teacher who said to just avoid hitting the strings you don't want to play. My present teacher and Justin both say to mute them. I guess it is up to you, but if you do get in the habit of muting them then you can not play them by mistake.

[JC]

Yes, I guess that would make sense.

Thanks Roy

[justinguitar]

you should do BOTH.

mute it and try and avoid it!

when playing with lots of volume, muting become VERY important!

[royp]

Thanks Justin.

Yes, of course the string that should be muted will make a sound when you have the volume turned up even if you don't hit it, because of resonance vibrations.

So yeah, mute it and avoid it, both.

[JC]

Yes Sir, will do! 

[royp]

   Even hitting a muted string will make a percussive noise, so I guess Justin commands and we obey. 

[JC]

Yes, we shall be good students!

And what do you prefer

1. looking a hot chicks in the audience or

2. watching you hand to miss the strings.

Hello
I do not know any songs. But you can make up your own songs. Just make sure you're in the right key. Say you want to right a song in the key of C. In the key of c major, the notes are C D E F G A B C. Those notes get numbers according to their position and interval within the key. If you want to make chords out of these notes then you must use a formula. The formula is numbers 1 4 5 are major and numbers 2 3 6 are minor. Number 7 is minor7b5. But i assume you dont know how to play one of those yet. lol
C d e F G a b
1 2 3 4 5 6 7
The lowercase stand for minor or minor7b5(you do not have to know what this chord is). The uppercase stand for major.

The formula is like that because you are only using notes from the key of C in the chords. You don't have to understand that right now though. Just if you know the formula then you can use chords to make your own songs.      Oh and i forgot. you can make any major chord into a dominant 7th.
   The key of G has more begginer chords in it but i am going to leave the figuring out of that one to you. Just write down the notes, number them and follow the formula. This is a big step in your guitar knowledge.
And with the song writing don't feel like you need a big long chord progression. There are a lot of three chord songs. It also sounds real cool to arpegiate the chords. That is to pick them out one note or so at a time. Have fun making music. Isn't that what you want to do anyway.

The dominant seventh chord is just like a major chord except that one of the root notes is changed to a flat seventh.

Guys a dominant 7 is a bluesy sounding note, so look into the 12 bar blues and make sure you get that blues shuffle going.
Quick example
E7 E7 A7 A7 E7 E7 B7 B7 A7 E7 B7 E7 go slow and get the feel right - blues is more about the feel than being perfect in your playing, but being fluid helps. Notice how the quick four at the end makes the song sound cool.
Some 12 bar blues songs to listen to:
Blue Suede Shoes, Rock Around The Clock, Johnny B Goode...
