Vertical vibrato

Justin has a Clapton style vibrato lesson as well. Worth seeking out as well (of course). LOL

This guy might have some valuable perspective on the pros and cons of different vibrato techniques.

That makes sense in physical terms.
If you place your finger on one point of the string you can change (incresase) the pitch by stretching it. Spatially there are 3 axes: x, y & z (aligned with the neck, aligned with the fret, and up/down toward the fretboard). The pivot and Clapton methods are variations of y, what I was suggesting is z.
The violin method (x) doesnā€™t really work on fretted instruments, as you would have to press it down to the fret first in order to get enough grip to increase/decrease tension on the string.

I enjoyed the Clapton method video with guitar in hand and laughed at the part where he said all students shake their whole armā€¦ watching my whole arm shake :rofl:

Another related question:
Are people able to discern the difference between vibrato on a guitar where pitch is raised and reduces to normal
Vs
violin, where pitch presumably oscillates between above and below pitch? :thinking:

This is the standard method on classical guitar (which is fretted, I believe :slight_smile:

I certainly canā€™t, but Justin does mention in his video that he can tell the difference between a bent string vibrato (which only oscillates down in pitch) and ā€œstandardā€ vibrato, which (typically) only oscillates up.

(I think my standard vibrato oscillates around the the in-tune note, i.e. both up and down. It needs plenty of work, in any case.)

And isnā€™t that what Justin meant in the video that you didnā€™t watch Brian that I postedā€¦or do you mean something else?

I love this discussion. Hereā€™s how I think about it.

By fretting the string, weā€™re effectively shortening its length, and by bending it (in any direction), weā€™re increasing the tension on it, both of which increase the frequency/pitch of the note being played. Vibrato essentially increases the tension/pitch briefly, returns to the initial fretted note, and repeats however many times you bounce it. I see no way to drop below the fretted note, because youā€™d have to decrease the tension or lengthen the string, and the fret provides the lower limit there (as @brianlarsen has said).

As Justin says, I think the ā€œclassicalā€ vibrato technique has some component of tightening/loosening the string tension by the friction of your finger pulling/pushing it along its length, but I also think thereā€™s a significant component of @brianlarsenā€™s Hard-pressed frets at work here. Itā€™s more difficult to keep the string pinned against the fret as you move your finger away from it, so you will naturally apply more force; that, in turn will stretch the string downward toward the fretboard. Itā€™s the difference between these two diagrams:

and

By oscillating between these two positions, weā€™re combining tightening/loosening the string directly along its length and ā€œbendingā€ it toward the fretboard then releasing it. I strongly suspect the latter is the greater effect. Weā€™ve all heard the change in pitch when we fret too hard or too far away from the fret.

Whatever effect we can get from ā€œpullingā€ the string toward the bridge with this method is the only mechanism I can see for bring the pitch below the fretted note.

Also remember not all frets are made equally.

Classic guitar and a lot of early guitars had very low and narrow frets.

Making this less an issue.

With nylon strings you can increase tension that way because they have very little tension to start with.

Modern electric or acoustic guitars tend to have a lot more fret, it helps lead/bending in general

Jim,

The way you ā€œwas doing itā€ immediately brought B.B. King to mindā€¦ maybe not his exact technique but close!
My thinking :thinking:ā€¦
If it works for B.B. , it works!!!

My 2 cents!

Apologies, my friend, but that relates to classical guitar with low tension, nylon strings.
Iā€™m afraid I ā€˜SantaClausedā€™ my beloved signature classical to my daughter and it now lives in Germany :cry: so I have no way of testing hypothesesā€¦ (Would you like me to tell you the Tommy Emmanuel story again? :rofl:)

Iā€™m lost (but itā€™s already way too late to think), but are you talking about acoustic vibrato all the time?

:joy: and :scream:

That was such a long time ago and there have been many possibilities in the meantimeā€¦so it would have been nice to do it againā€¦sometimes :rofl: :joy:

But Iā€™m really confused now and Iā€™m just too tired to read it again, Iā€™ll do it tomorrowā€¦ :dizzy:

I mean from 3;15 in the video is methode to and from the bridge and nut ?

Ok, so I did try it and yes, I can hear some vibrato coming out. However, itā€™s nowhere near the amount of vibrato you get when doing one of the conventional vibrato methods.

And it makes sense if you think about it. How much are you elongating the string when you push it down against the fretboard? About the height of the fret wire, which is only a fraction of the amount (typically) when you vibrate the string from side-to-side.

I also did a little test: I tried to measure how much the pitch of a string increases when pushing it down hard. Using my tuner, I fretted the D string at fret 5 giving me a G note. Using a very light touch, I tuned the string. Then I pushed down very hard (careful not to move the string sideways) on the string and the tuner says it increased either 0 or 1 unit (it was not too stable). On my tuner thatā€™s at most one tenth of a semi-tone or 10 cents. A 10 cent difference in pitch is sort of at the edge of human perception (according to my 10 minutes of research on Wikipedia), but how many cents we can perceive varies from person to person and depends on the pitch itself, the timbre, etc. One interesting thing I noticed: the string goes more out of tune if I push down far away from the fret wire. I could consistently get 10-20 cents out-of-tune with sloppy fretting technique (this was true even if not pressing down hard).

Anyway, the point is, thatā€™s a very small shift in pitch. Iā€™m guessing that when people perceive a shift in pitch when pressing down too hard, they are actually imparting some sideways pressure on the string, which contributes to the increase in pitch.

Anyway, my little test makes me think that @brianlarsen 's in-out vibrato (I would like to trademark this name) is also caused by accidental sideways movement of the string.

If you really want to see a master at vibrato, find a video/film of Paul Kosloff (Freeā€¦early 70ā€™s). There is an old tale, regarding Free, as the opening act for Blind Faith. While touring in the States. during a sound check at the Forum in Los Angeles, Clapton was sitting back in the shadows, in a floor seat, listening to Freeā€™s sound check and was blown away by Kosloffā€™s sound and vibrato technique, later to take Kosloff aside to learn the technique.
Evidently, Kosloff had learned and developed the technique while taking instruction for cello, when he was a young lad.

Just had a quick look on the Google-beast
Bit of trivia:
Violin vibrato modulates between lower pitch and the played note (by lengthening the distance from finger to bridge) as opposed to guitar which raises the pitch by increasing tension, which means it is impossible to play violin style vibrato on a guitar :wink:

Interesting. It seems on a violin you get vibrato by changing the exact position where the string is pressed against the fingerboard and hence the length of the vibrating string. This is not possible on guitar, because the fret position defines the length of the vibrating string.

Classical vibrato on guitar is achieved by increasing (and decreasing?) the tension on the string by pulling it (and pushing it?) along the direction of the string.

They look similar when performed, since the finger moves back and forth along the string direction. But the physics is different. Interesting!

Aha, So also impossible on an acoustic because it also has frets and so Justin explains it incorrectly here at 2:55

Do you now understand my confusion after these words of yours and he even does it on the electric one, but by moving that finger in that way he does nothing other than press the strings harder and softer on the fretā€¦ Was THAT so difficult to explain to me before sleeping?

You can play the violin style of vibrato on the guitar but the effectiveness will be limited. At a minimum it can add some warble or sustain. You can sharpen the note a bit (for better or worse) depending on how hard you push down.

I think that itā€™s safe to say that over the years, guitarists have employed every possible method to vary the pitch of a note. In fact the ā€œsoundā€ of many of our favorite guitar heroes is partially defined by how they use vibrato. It probably makes sense to just experiment with all the different methods, figure out what works best for you in the style of music you play and then use that.
