What Are Glottal Repeats? The Coordination Challenge
Glottal repeats involve singing the same pitch multiple times in rapid succession on a vowel sound, with no consonants to separate the repetitions. Instead of "ha-ha-ha" (where the "h" creates separation), you sing "ah-ah-ah," using only glottal stops to articulate each repetition.
A glottal stop is the brief closure of your vocal folds that stops airflow momentarily. It is the sound in the middle of "uh-oh." In glottal repeats, you open and close your folds rapidly on the same pitch, creating distinct attacks without consonant articulation.
This exercise isolates vocal fold coordination from breath pulsing and consonant shaping. Your diaphragm maintains steady pressure while your folds do all the articulation work. This builds the specific coordination needed for melismatic runs where multiple notes occur on a single syllable.
Building Fold Closure Speed and Stamina
Your vocal folds are muscular structures capable of rapid movement. In conversational speech, they open and close up to 250 times per second (for higher pitches). But most people have never trained them to open and close rhythmically at will.
Glottal repeats build that conscious control. At first, your folds may feel clumsy or sluggish. Repetitions may sound uneven or mushy. This is normal. You are developing neuromuscular pathways that most people never use.
Start slowly (one repetition per second) and focus on clean, complete closure between each repetition. You should hear a distinct gap of silence between each "ah." If the repetitions blur together, you are not achieving full closure.
The Pattern: Repeated Notes on Single Pitches
Start on a comfortable middle pitch. Sing four to eight repetitions of "ah-ah-ah-ah" on that single pitch, using glottal stops to separate each repetition. Breathe, then repeat on the same pitch or move to a different pitch.
Keep each repetition short and crisp. You are not sustaining the vowel; you are pulsing it. Think of staccato eighth notes rather than sustained whole notes.
Practice on different vowels. "Ah" is easiest because it requires an open throat. "Ee" is harder because the high tongue position interferes with glottal closure. "Oh" and "oo" fall somewhere in between. Training on various vowels builds versatile coordination.
Avoiding Tension in Fast Repetitions
As you increase speed, your tendency will be to tense your throat to compensate for inadequate coordination. Resist this. Tension slows your folds down and causes fatigue. Relaxation allows faster, easier movement.
Focus on the sensation of your folds bouncing lightly against each other, not slamming hard. The closure should be gentle but complete. Harsh glottal attacks create vocal damage over time. Clean, light attacks build stamina without strain.
If your throat feels sore or tired after practicing glottal repeats, you are attacking too hard. Back off the intensity and focus on lightness. The exercise should feel athletic but not painful.
From Exercise to Musical Application: Runs and Riffs
Glottal repeats appear constantly in melismatic singing. When you sing multiple notes on a single syllable (like Gospel runs or R&B riffs), you cannot use consonants to articulate each note. You must use glottal separation.
Listen to singers like Christina Aguilera, Mariah Carey, or Beyoncé executing fast runs. Many of their note separations use glottal articulation. Without this skill, runs sound sloppy and undefined. This same coordination powers gospel melismatic agility, where fluid thirds runs require clean note separation at high speed.
Practice applying glottal repeats to actual melodic patterns. Sing a simple arpeggio (do-mi-sol-mi-do) on a single "ah" syllable, using glottal stops to separate the notes. Then try more complex patterns like scalar runs or interval leaps.
Combine glottal repeats with diaphragmatic support from the pulse on F exercise. Your abs provide the energy foundation, while your folds provide the rhythmic articulation. Together, these create professional-level staccato and agility technique. Musical theatre performers can take this further with broken thirds agility patterns to train the interval leaps found in contemporary scores.
