What do a trembling hand, an emotional speech, and a soaring operatic note have in common? Vibrato.

In this episode of The Voice Science Podcast, we dive deep into the real science behind vibrato in singing—what it is, how it happens, and why it’s not just a stylistic choice, but a neuromuscular phenomenon grounded in biology.

You’ll learn:

• ✅ What causes vibrato (and why we don’t fully know)

• ✅ The leading theory: The Reflex Resonance Model

• ✅ Why some singers struggle to find their vibrato

• ✅ Exercises that actually work (and which ones to skip)

• ✅ How vibrato relates to balanced vocal technique

We explore insights from voice scientists like Ingo Titze and John Nix, and break down the rate and extent of vibrato in terms every singer can understand.

If you’re a singer, vocal coach, or just curious about how the voice works, this episode is your guide to discovering vibrato through better technique—not gimmicks.

🎙️ How to Sing with Dynamics: Mastering Loud and Soft Singing | The Voice Science Podcast

Want more vocal power without straining? Learn the real science behind loud and soft singing—and why it’s not just about more air or effort.

In this episode of The Voice Science Podcast, we’re breaking down the key elements that shape your vocal dynamics: subglottal air pressure, vocal fold mass and tension, and vocal tract shaping. You’ll walk away with a clear understanding of how to control your volume with precision—not just force.

We also debunk some of the biggest myths in vocal training, like:

• “More air = more power”
• “You just need to sing louder to sound better”

You’ll get 3 powerful exercises to help you build dynamic control across your range, including:

1. Octave scales to balance intensity from low to high
2. Soft chest voice exercises to build finesse at low volumes
3. The legendary messa di voce to master smooth crescendos and decrescendos

Whether you’re training for auditions, performances, or just better technique, this episode gives you the tools to sing smarter—and healthier.

The Voice Science Podcast | Episode [6]

Think there’s only one right way to breathe while singing? Think again. In this episode of The Voice Science Podcast, we debunk the myth of a one-size-fits-all breath and explore how different breathing strategies impact your voice, performance, and vocal health.

Join Drew as we break down the anatomy of inhalation, explain the four main types of breathing for singers—diaphragmatic, thoracic, clavicular, and balanced—and explore how each breath type supports different vocal styles and artistic goals. Whether you’re a classical soprano preparing for a long legato phrase or a musical theatre singer belting onstage, understanding the right breath for the moment is key to vocal freedom.

🔬 Learn:

• Why the diaphragm is always involved—no matter what type of breath you take
• When “belly breathing” helps (and when it doesn’t)
• How clavicular breathing fuels high-stakes, emotional moments
• Why balanced breathing can be both a superpower and a trap
• How thoracic breathing might be your ideal default setting

Ever felt like you just can’t sing or speak another word? That frustrating tired, strained feeling in your voice is called vocal fatigue—and it happens to singers, teachers, and professional voice users alike. But what’s really going on when your voice feels exhausted?

In this episode of The Voice Science Podcast, we’re breaking down:

✅ What vocal fatigue really is (Hint: It’s NOT your vocal folds wearing out!)

✅ The hidden muscles that contribute to vocal fatigue

✅ Why dehydration makes vocal fatigue worse

✅ How long it actually takes for your voice to recover (and why rest is crucial)

✅ 5 science-backed strategies to prevent and recover from vocal fatigue

🎧 Listen now and learn how to keep your voice healthy, strong, and resilient!

How to Prevent & Recover from Vocal Fatigue

🗣️ Reduce Vocal Dosage – Your vocal folds slam together thousands of times per second when you speak or sing. Reducing excessive strain can help.

💧 Stay Hydrated – Studies show hydration doubles vocal endurance!

⏳ Allow Recovery Time – Your vocal folds recover 90% within a few hours, but full recovery takes up to 72 hours.

🎶 Increase Brightness in Speech – Using Ring & Twang (covered in Episode 4!) helps reduce vocal effort.

🔊 Raise Your Speaking Pitch Slightly – Speaking too low increases strain and makes you work harder to be heard.

Have you ever wondered how some singers have voices that seem to soar effortlessly, cutting through the mix and filling the room? The answer lies in brightness—a crucial acoustic phenomenon that enhances resonance and projection. In this episode of The Voice Science Podcast, we’re diving deep into the science of Ring and Twang, two vocal techniques that can transform your sound and help you sing with more clarity, power, and ease.

What You’ll Learn in This Episode:

✅ What is brightness in singing? (Hint: It’s not just about being “loud!”)

✅ The difference between Ring & Twang—and why both matter

✅ How laryngeal height determines whether you use Ring or Twang

✅ Common myths about brightness, including why it’s not the same as nasality

✅ 3 powerful exercises to develop Ring & Twang for better vocal control

🎧 Listen now and discover how a small shift in your technique can revolutionize your voice!

Ever wondered why some notes feel effortless while others crack or don’t come out at all? The answer lies in phonatory threshold pressure (PTP)—the minimum air pressure needed to start and sustain sound. In this episode of The Voice Science Podcast, we break down what PTP is, how it’s calculated, and why it matters for singers.

Discover how PTP affects vocal efficiency, vocal fatigue, and even vocal warm-ups. We’ll also debunk common myths about breath pressure, including the idea that “more air is always better” and that pushing harder is the key to volume. Instead, learn smarter, science-backed techniques for singing powerfully without strain.

👉 Try the simple vocal exercise in this episode to explore how little pressure you actually need to sing clearly. Plus, get a sneak peek into next week’s deep dive into ring and twang—two powerful tools for enhancing your voice without overworking your breath.

🔬Phonation Threshold Pressure Formula:
Pth = 0.14+.06(Fo/|Fo)^2 kPa
