Got down the basics and ready from some techniques and articulations? Here you can learn some of the basic advanced techniques (Yes, it's an oxymoron, deal with it).
Vibrato is a required technique for all intermediate and advanced players. Vibrato adds color to the rather dull sound produced when not using vibrato. Vibrato is defined by the rotational or circular movement at a certain point on the fingerboard. To practice this, start of by moving your finger up and down the fingerboard, creating a glissando effect. Then, gradually make the range of your finger sliding more and more narrow, until you are focused on one point. Vibrato is not a technique you get right off the bat. It will take a some practice to get and perfect. Below are some videos to help.
Harmonics are created when vibrato multiple parts of the string. It is preformed by lightly placing the finger on top of one of the strings and bowing. One of the major harmonics is found at the half point of the string. From that point you have cut the string into two. Chose one of those halves and cut that half in half. You have now found another harmonics. Harmonics are found by cutting the string into multiple equal parts. You can find more info on harmonics here.
Double stops are made by bowing two strings/notes and the same time. Similarly chords can be formed by bowing multiple strings at the same time but a bit differently. When performing chords on the cello, we can only bow two strings at the same time. In order to bow a chord, which is comprised of three or more notes, we have to roll our bow from one note, the other two. For example: one of your notes could be on the G string and the other two could be on the D and A string. You can play the chord one of two ways. Either play the G string note and roll the bow to a double stop between the two notes on the D and A string. Or double stop the G and D string note, and roll the bow into a double stop between the D and A string notes.
There are plenty different bowing techniques that produce different sounds, moods, and colors. Here are just a few.
Sul Ponticello is performed by bowing extremely close to the bridge. Doing this creates a ghostly-like sound.
Sul Tasto is performed by bowing above the fingerboard. It creates a moody and timid like sound. Here is a site that covers sul ponticello and sul tasto.
Ricochet is performed by throwing the bow onto the string, creating a, pause for effect, ricochet effect. Throwing different points of the bow on to the strings will produce a different number of notes played
Spiccato is performed by bouncing the bow on the string, cutting the note short.
