# Picking a guitar string of fixed length to get any nth harmonic, is it possible?

In physics textbook, we can calculate the nth harmonic of a vibrating string of a fixed length. How can we do this in a real guitar?

For example, if I just pick a single open string, how can I get any arbitrary harmonic for this?

More precisely,

• the first harmonic has 2 nodes and 1 anti nodes
• the second harmonic has 3 nodes and 2 anti nodes
• the nth harmonic has n+1 nodes and n anti nodes
• What is unclear about en.wikipedia.org/wiki/Guitar_harmonics ? For video lessons on how to actually perform various kinds of harmonics see justinguitar.com/en/TE-000-Technique.php You have to scroll down a bit. Commented May 27, 2015 at 13:03
• @nephente: You mean that I have to change the length of the vibrating string by pressing the string against the fret? If so, you are talking about different scenario. I want to keep the length of the vibrating string remain unchanged. Commented May 27, 2015 at 13:07
