The harmonic technique of electric guitar is an important means to add rich colors and unique sound effects to the performance. The following are some ways to use harmonic techniques to create unique sound effects.
Clever use of natural harmonics
Natural harmonics are produced by touching and plucking the strings at specific positions, which are usually integer fractions of the length of the strings. By using natural harmonics at different frets, clear and bright high-pitched harmonics can be obtained. For example, playing natural harmonics at the 12th, 7th, and 5th frets will produce an ethereal and crisp sound similar to the sound of a bell. The performer can choose the appropriate frets and combinations according to the emotion and atmosphere of the music to create a unique melody line, adding an otherworldly feeling to the music.
Extended application of artificial harmonics
Artificial harmonics are produced by touching specific nodes on the vibrating strings with fingers and plucking the strings with a pick at the same time. Compared with natural harmonics, the position of artificial harmonics is more flexible and can be achieved at any fret. By changing the position of touching the strings and the strength of plucking the strings, a variety of harmonics with different timbres and pitches can be obtained. For example, playing artificial harmonics near the bridge will produce sharp, bright and penetrating sound effects, which are suitable for creating a tense and intense musical atmosphere; while playing near the fingerboard will produce relatively soft and warm harmonics, which can be used for lyrical and soothing passages.
Fusion of harmonics with other techniques
Combining harmonic techniques with other playing techniques can create more diverse and unique sound effects. For example, adding harmonics while using the bending technique can produce a unique sound with both pitch changes and harmonic ethereal effects, adding more emotion and expressiveness to the melody. For another example, adding harmonics in time during the strumming process can make the timbre of the entire chord brighter and more open, and enhance the layering and three-dimensional sense of the music.
Modification of harmonic sound effects by effects
Using effects to modify harmonics can further expand the possibilities of harmonic sound effects. For example, using a delay effect can make harmonics echo, creating a sense of space and atmosphere; using a reverb effect can make the harmonics sound fuller and richer, making them more prominent in the entire music space. By adjusting the parameters of the effect, such as delay time, reverb depth, etc., you can create a variety of unique harmonic sound effects according to different musical styles and creative intentions.
Through the proficiency and flexible use of electric guitar harmonic techniques, as well as the clever combination with other playing techniques and effects, players can create a variety of unique and charming sound effects, adding infinite possibilities and creativity to electric guitar performance.
