C Sharp Dominant Seventh Guitar Chord Lesson
In the following acoustic guitar lesson, you will learn how to play 5 advanced voicings of the C#7 Guitar Chord (also know as Db7, C Sharp 7, C Sharp Dominant Seventh, D Flat Dominant 7).
The C Sharp Dominant Seventh Chord is found by locating the 1, 3, 5 and b7 positions (C#, E#,G# and B) of the C# Scale: C#, D#, E#, F#, G#, A#, and B#. The “b7” symbol means that we take the 7th position of the C# scale (B#) and we flatten it by 1/2 step giving us our “B” note.
So the notes of the C#7 Guitar Chord again are: C#, E#, G# and B
Here is a key that will help you read the chart:

Everything on the above chart should be self explanatory, except for the last three in the third column. They may need a bit of explaining. The O, or open symbol, simply means that you do not press down on any notes on that string. The X means you do not strum that particular string. The Barre symbol means you need to barre that particular fret. When you barre a fret you are pressing down on multiple strings at the same time with one finger.

Chord Playing Tips
Be sure that you are pressing down on the strings hard enough and play each string one at a time to make sure you have a nice clean sound. If any of the strings buzz or sound muted, then something is not right.
