Shifting to Another String

Shifting-on-the-same-string is somewhat different to shifting-to-a-different-string. The concepts of  “Same-Finger Shifts“, “Assisted Shifts” and “Scale/Arpeggio-Type Shifts” that were discussed in “Finger Choreography” are mainly applicable to shifts on the same string, because when we shift to a different string, we can normally put the” new” finger down on the “new” string before the shift starts. This means that most shifts to a new string can be – and normally are – felt and measured simply as same-finger shifts, even when the finger previous to the shift is not the same as the target finger. This advantage of being able to place the new finger before the shift is why shifting to another string is often easier than shifting on the same string.

Shifting to a new string does however introduce some new complications that we don’t have when shifting on the same string:

  • we need to know (decide) on which string – “old” or “destination” – we will “do” the shift (glissando)
  • we need to do a slightly more complicated mathematical calculation relating the shift distance to the interval distance because the change of string distorts this relation
  • for shifts with the same origin and target finger, we somehow have to get our finger across from the original string to the new string during the shift.

Let’s look now in more detail at these special characteristics of shifts to a new string:

SHIFT ON OLD OR NEW STRING?

In the first of the above examples, no matter what fingers we place on our origin and target notes, in order to achieve the smooth legato we will always do the shift as a “same-finger-shift-on-the-new-string”. In the second example however we have a lot more choices as to how we might do the shift. Now, because our shift (glissando) is silent, we can choose to do the shifts on either the new string (on the new finger) or on the old string (on the old finger). We could even decide to do the shifts as “scale/arpeggio-type”. In other words, not only do we need to choose on which string we will make the shift, but also we now have a greater choice of finger choreography and of intermediate notes.

Example 1 uses “same finger shifts on the target string”, example 2 uses “scale/arpeggio-type shift to the target string”, example 3 uses “scale/arpeggio-type shifts on the lower string”, while example 4 uses “same-finger-shifts-on-the-old-string” (= assisted shift to new string!). Yes, this sounds quite complicated ……. but that is the way it is, when shifting to a new string!!

THE GLISSANDO IN SHIFTS TO A NEW STRING: DOUBLY IMPORTANT

As with shifts on the same string, we need to be able to “hear” (imagine) the shift interval in our heads even if we decide to make no actual audible glissando during the shift. Practicing all shifts with an audible glissando programs the brain and the hand so that even when we do the shift silently, we can still hear it in our imagination. This is especially important for shifts to a different string, because here the shift distance no longer corresponds to the interval size.

In a shift to a new string, not only does the glissando no longer correspond to the entire shift interval, but also, to complicate matters, the audible glissando to the new note can be “outside of the shift interval”. This occurs when we shift to a higher position on a lower string, as in the first and third bars of the above example. In other words, while the note progression goes downwards (or stays unison), the glissando to the new note goes upwards.

ADDING DOUBLE-STOPS AS A PRACTICE AID

For practicing shifts to a neighbouring string, adding a doublestop just before the shift is a great help, both to hear what is going on and to ensure that we do actually place the new finger before the shift. This means simply that, just before our shift, we will sound (normally with the bow) the “new” finger (and string) simultaneously with the “old” finger (and string). Sound complicated ? It isn’t ! An example will show this better than 1000 words:

to new string with dblestop

Most commonly we will be shifting on the new finger on the new string, but not always. Sometimes we may have to shift on the “old finger and string” but the principle of adding a double stop remains the same:

to 3rd string with dblestop

SHIFTS TO A NEW STRING WITH SAME TARGET AND DESTINATION FINGERS

A “same-finger” shift on the same string is the easiest type of shift to do. But if the is to a different string, this situation is reversed. To illustrate this, look at the following examples:

These shifts are basically like fifths with a shift in the middle, and we know that fifths complicate matters greatly on the cello. Here, we will need to get the finger over to the new string during the shift, because playing both “origen” and “target” notes as capo-fifths (one finger stopping the two strings simultaneously like a guitarists “capo”)  is rarely a good option from the point of view of vibrato, sound quality and intonation.

If we are shifting to the higher string, then moving the finger over to the new string during the shift is not particularly difficult. Problems arise when we need to shift to the lower string on the same finger, as occurs in the second part of each of the above bars. For anatomical reasons it is impossible to make this movement truly legato, so we simply do our best to avoid these types of fingerings in legato passages.

We can summarise this difference in the following examples:
