Hybrid picking is a guitar-playing technique that involves picking with a pick (plectrum) and one or more fingers alternately or simultaneously. Hybrid picking allows guitar players who use a pick to perform music which would normally require fingerstyle playing. It also facilitates wide string leaps (e.g. from the sixth string to the second string, etc.) which might otherwise be quite difficult. The technique is not widespread in most genres of guitar playing (though notable exceptions exist), but is most often employed by rockabilly, country and bluegrass flatpickers who play music which occasionally demands fingerstyle passages. Hybrid picking was developed by and became the signature technique of Isaac Guillory.
