The c7 chord Notes

The c7 guitar chord will sound quite heavy to you and the reason is probably that the chord is based on three dominant notes. The chords are made in the root position and the stack of notes in the third position. You may break it down to a root position, three-note chord, and a  seventh chord is used which is seven intervals away from the root of the chord. 

Being a dominant chord, the c7 guitar chord sounds strong. The names of the notes are similar in the case of c7 chord guitar and c7 chord piano. It has little differences between the three-note chord and c7 chord ukulele as it has one note added to the three-note dominant chord which has one root, a major third, and lastly, a perfect fifth, Only in the case of the four-note chord we add another note which is not dominant and is four notes away from the root. 

Playing the c7 chord piano  

1. The pinky finger, middle finger skipping the ring finger, the index finger, and the thumb are only used for both hands.
2. The third note in piano and the fourth note come together to form a third.
3. There are two variations of the third note chord.
4. As the third note can be major or minor, the chord also has similar variations.
5. The dominant 7th chord is 5 degrees away from the previous major key and it is called the 7th natural.

Playing the C7 guitar chord  the C, E, G, and Bb are played, also you may notice the player skip the G sometimes.  To play the c7 chord ukulele  the same formula is used, no note is skipped and the player should follow the convenient formula of 135B7. To get the seventh degree of the scale after the root C the note one-half step lower to B is played. 

Considering the formula for the major chord dominant. The dominant chord is formed when after the root chord, C, the next note tends to be up the perfect four. Moving up C, the perfect four steps lead you to the perfect fourth. Closely seeing you can make out that the c7 chord piano is one major third and then two of minor third one over another.

Inversions

If you want to apply an inversion or you may call it a voicing, simply go one octave above C. You will now have to play the chords as EGBbC if you go by the sequence. In this way, if one goes above another octave, the second inversion is the results. The keys played here are GBbCE and this is two octaves higher than the root position. Similarly, the second inversion can be played by going up three octaves from the actual C root position and the keys played, in that case, are BbCEG respectively. 

Playing c7 guitar chord:

1. Place the index finger on the first fret of the B string.
2. The middle finger is placed on the second fret of the D string.
3. Your ring finger should be on the third fret of the A string.
4. Lastly, place the pinky on the third fret of the G string.
5. Here you need to play all of the guitar strings in c7 chord guitar except the low E string

As you press the strings in the right positions as mentioned above and then you play all strings omitting low E strings, the sound is of a heavy guitar chord c7. 

When in root C position the CEGBb is pressed together. The first three keys are white ones and the fourth Bb is a black key. While playing inversions with the c7 chord piano move an octave up from each position. This means each key in the inversion lies an octave above the root key position. Inversions are generally added because they sound better and often at the end of a song they sound beautiful with different inversions of the c7 chord piano. 

Other Instruments

Playing the c7 chord mandolin is quite similar to the pattern we see in the case of the c7 piano chord or the guitar c7 chord. The major and minor seven chords sound very different. It is very important to remember the scale shapes while playing the C7 guitar chord. The dominant 7 chord has a major chord with a minor interval chord on top of it.  The variations of major and minor sounds like a battle and snatches a lot of attention, than when playing only major or only minor.
