vibrato arm
C1/C2Technical, Musical Slang
Definition
Meaning
A lever attached to the bridge of an electric guitar, allowing the player to vary the tension of the strings to create pitch fluctuations (vibrato) or dive-bomb effects.
A mechanical device on a guitar (also commonly called a 'tremolo arm' or 'whammy bar') that temporarily alters the pitch of the strings by raising or lowering the bridge. While often called a 'tremolo arm', it technically controls pitch (vibrato) rather than amplitude (tremolo).
Linguistics
Semantic Notes
The term is somewhat of a misnomer in common usage. Purists note that 'vibrato' is a modulation of pitch, while 'tremolo' is a modulation of volume. The device creates vibrato, but the term 'tremolo arm' is historically entrenched due to early marketing by guitar manufacturers like Fender.
Dialectal Variation
British vs American Usage
Differences
The term 'vibrato arm' is slightly more precise and used by knowledgeable players in both regions. 'Tremolo arm' is equally common, especially in the US due to Fender's 'Synchronized Tremolo' and 'Vibrato' unit names. 'Whammy bar' is a very common informal term in both.
Connotations
In formal technical writing, 'vibrato arm' or 'tremolo system' may be preferred. 'Whammy bar' carries a strong connotation of rock and extreme effects.
Frequency
'Whammy bar' is likely the most frequent term in casual conversation among guitarists. 'Vibrato arm' is frequent in product specifications and reviews.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calques like 'рука вибрато'. The standard Russian term is 'тремоло-система', 'рычаг тремоло', or colloquially 'вибрато'.
Common Mistakes
- Confusing 'vibrato' (pitch) with 'tremolo' (volume). Saying 'tremolo pedal' when meaning 'vibrato pedal'. Calling the device simply 'the vibrato' without 'arm' or 'bar' can be ambiguous.

FAQ
Frequently Asked Questions
Yes, they refer to the same physical device. 'Whammy bar' is the common slang term, while 'vibrato arm' or 'tremolo arm' are more formal names.
This is a historical misnomer popularized by Leo Fender's early marketing in the 1950s. He labelled the system on his Stratocaster 'Synchronized Tremolo', and the name stuck in common parlance, despite the device controlling pitch (vibrato), not amplitude (tremolo).
No. Many models, like the Gibson Les Paul or Telecaster variants, feature a 'fixed bridge' with no moving parts. Guitars with vibrato arms are often chosen for genres requiring pitch-bend effects.
A 'floating' vibrato arm setup allows the bridge to be moved both downwards (to lower pitch) and upwards (to raise pitch). A 'decked' or non-floating setup only allows downward movement. Floating setups offer more expressiveness but can be trickier to keep in tune.
