Vocal Function Exercises: What’s the Fuss?

VFEs If You Please…

If you’ve ever wanted to balance your voice by improving strength, endurance and coordination you may have come across vocal function exercises(VFEs). These are a series of 4 exercises that can be modified multiple different ways to balance your vocal subsystems. They were initially conceptualized by Dr. Joe Stemple and have been the subject of multiple research studies in the area of voice.

What Do I Do?

All 4 exercises consist of a warm-up, a stretch, a contract and a power section. Warming up is sustaining the vowel “eeeeee” as long as you can with a forward focus on one breath. Stretch and Contract are pitch glides with a modified oral and laryngeal cavity shape (to either create back-pressure, or modify with a glottic closure increaser.) Power consists of 5 separate notes, 1-5 on the major scale, usually starting on “C” but that can be modified with the same modified oral/laryngeal cavity.

Why Do We Do?

Positive effects have been seen in multiple areas of deficit like in disordered voices, functional dysphonia, vocal cord lesions and muscle tension dysphonia. Surprising to some, VFEs can also improve singers with no injury and no voice complaints, including singers in singing lessons or as warmups.

Trouble with VFEs?

There are many ways to modify VFEs to fit your need from the pitches chosen to the resonant cavity posture. There are ways to use technology like pitch monitor apps that track fundamental frequency (F0) as well as coaching needs to make sure you aren’t straining to produce the target sound. Modification has been researched to continue to be effective at reaching goals vocalists has for themselves.
