How to strum a chord
There are a few different ways to strum a chord. With strumming we are referring to the right hand (if it’s a not a left-handed guitar) technique used to get sound from the guitar by playing several strings instantaneous.
Playing guitar is about making a harmony of two hands in motion. There are three main methods for strumming the strings:
- You play with the inside of your thumb.
- You play with your index finger nail.
- You use a plectrum.
Nothing is really right or wrong. It all depends on your own preferences and the effect you want to accomplish. The recommendation is to try all three methods to begin with. It is both a question of preference and what will sound best in certain situations.
Using the thumb or index finger
You will get a somewhat muffled sound using your thumb and a kind of crispy sound when strumming with your nail. Something to consider is that it could be harder to play accentuated upstrokes with your thumb than with your fingernail or a plectrum.
Using a plectrum
The advantage using a plectrum is that you effortlessly get between the strings without touching them. This refers mainly to when you’re plucking and not strumming. But regardless what you are playing for the moment it always good to learn to play with a plectrum. For best strumming practice, use a thin plectrum for strumming.
It's unusual to use a plectrum on a classic guitar - it won’t sound very good and neither is a plectrum needed due to the space between the strings. Plectrum is on the other side common on steel-stringed and electric guitars.
Depending on the position you are strumming on the guitar the sound will differ. There are mainly three positions and they are sometimes referred to the Italian terms: normale - you play over the sound hole; sul tasto - you play nearer the fretboard; sul ponticello - you play nearer the bridge.
Strumming with speed
Sometimes it sounds better if you strum with speed. It can be hard to strum fast in the beginning, but you will learn. What you should think of is to not move your whole under arm from the elbow but instead move your hand from the wrist. This is much more economical and serves the speed since you will be able to strum up and down will small movements.
