For instance, if we play with only the thumb of our picking hand as opposed to a plectrum we get one type of sound. If we play only down strokes with our thumb we get a different sound again.

Let's delve into this further as it is important.

If we play with our index finger, middle finger, a plectrum on the pointy end, on the fat corner, on the fat end, upstrokes, down strokes, whatever, we can make all kinds of sounds. In fact, there are so many possibilities we may never get to them all in our lifetime.

Hopefully you see where I am getting at and we haven't even discussed the fingering hand yet nor have we discussed any particular notes, pitches, dynamics etc...

Don't let that stop you. Start learning this now and you will be happy you did.

Ok what's next?

Select 3 notes and work with only them while thinking about the spoken voice and how you would convey three words in a sentence. Think about how by changing the phrasing and articulation of our three words, or notes, we can change the meaning of them entirely. In fact pick an actual 3 word sentence and speak it with your guitar rather than using your voice. This is where we truly start learning melody.

If we were to find someone we don't know and say to them; "What is your name?" We would get a response. Don't forget that a non response is also a response. We must realize the actual response we get is dependent on how we phrase and/or articulate our words and realize that we can control this response only if we understand its relationship to our actual question.

I'll explain. If we were to say those exact words in a teasing, tormenting and antagonistic manner we would get one response. If on the other hand we were to use an openly friendly demeanor we get an entirely different response all together.

By doing this simple thought exercise we realize that using the exact same words spoken in different ways produces vastly different responses.

By observing, understanding, and practicing this behavior we can learn to exploit and utilize this technique to our advantage to allow the full potential in our guitar playing that invokes the response were seeking, whatever that may happen to be.
