We’ll now play the scale of C, The major scale of C has no sharp or flat notes, it has plain notes. The notes in scale of C are C, D, E, F, G, A, B

In any scale the 3rd and 4th note are separate by half note and same goes with the 7th and 8th note.
So when incrementing the frets, whiel playing the 4th note, just increment the 3rd note by 1 fret.

Let us play them in this fashion.

e||----------------------|----------------------|-------0----1----3----|
B||----------------------|------------0----1----|--3-------------------|
G||----------------------|--0----2--------------|----------------------|
D||-------0----2----3----|----------------------|----------------------|
A||--3-------------------|----------------------|----------------------|
E||----------------------|----------------------|----------------------|

--5----7----8----8----|--7----5----3----1----|--0-------------------|

All the notes have to be played in a down strokes. Play very slowly and at regular interval.

Let every note ring

Practice this 20-30 times till you can play the whole thing easily.

Alternate Picking
Now, that you can play the Note of C easily, let us start with a new way of picking strings… “Alternate Picking”
For alternate picking, every note you play, you pick in the opposite way to which you played the initial note.
ie. Start the C note by playing a down-stroke, the next note is the open String d, this you pick in up-stroke, then the E note you pick it in down-stroke, and so on…

You must grab this picking … So to start with… you do it very slowly, see every note that you pick, and register that note in your mind, and while playing that note try to find out the next note position and the type of stroke that has to be played.

Chords in Scale of C

[Tonic / Root / Key Note]    [Sub-Dominant]    [Dominant]    [Dominant 7th]
C                                  F                 G             G7
|                                  |                 |
Am                                 Dm                Em

Here is how to play each chord. Here the notations are each no. indicates finger no. 1 is the index finger, 3 is the ring finger, etc. The 0 at the begining denotes play open string. and x means do not play the string, or mute it. Each horizontal line is a fret.

You see 2 notes are to be played by the index or 1st finger, this means you need to bar the first finger, ie fret the e and B strings with 1st finger.
