Vocal Practice Guide

Told my pitch is unstable

💡 Recommended Practice Method

Train your "listening ability" first with Interval Recognition.

First, learn to accurately hear the interval between two notes. You cannot match a pitch you cannot hear.

Why This Practice Is Necessary

か。There are two main causes of unstable pitch: either you cannot hear it or you cannot produce it...

In most cases, the problem is not being able to hear correctly. If you do not know the correct pitch, you cannot match it. You need to train your listening ability first.

Scientific Background

Vocal Pitch Control: The Auditory-Motor Loop

Vocal intonation relies on a sophisticated auditory-motor feedback system involving both anticipatory and corrective mechanisms.

Feedforward control: Before phonation, the brain activates an internal motor program specifying laryngeal muscle configurations for the target pitch. Without a well-developed internal model, singers must rely on real-time correction, which introduces latency and makes accurate intonation nearly impossible on fast passages.

Feedback control: The auditory system monitors the produced pitch and compares it against the target, enabling real-time adjustments. Note that what you hear of your own voice is a mix of air-conducted and bone-conducted sound, which boosts low frequencies and attenuates highs — producing a timbral difference rather than a uniform pitch shift (Reinfeldt et al., 2007). Recordings sound unfamiliar mainly because of this timbre change, not because the pitch is offset by some fixed Hz amount.

Why ear training is essential for singers: Without internalized pitch references, the feedback loop has no target. Interval training builds the auditory templates necessary for the error-detection system to function. You cannot correct toward a target you cannot internally audiate.

Recommended Practice Method

Feature: Interval Recognition

💡 "Listen → Sing" Combined Practice

When you hear an interval in the app, try singing it out loud before selecting the answer.

This trains the "listen → recognize → vocalize" circuit simultaneously. Vocalizing, not just listening, accelerates retention.

Build a "hear-and-produce" baseline

Build internal interval templates with Interval Recognition, then close the loop with recording.

Can't sing when the key changes

💡 Recommended Practice Method

Train your "relative pitch" with Interval Recognition.

By memorizing "this interval" instead of "this pitch," you can sing based on the relationship between notes regardless of key.

Why This Practice Is Necessary

。You can sing in the original key but struggle when it changes. This is because you memorized the "absolute pitch".. gemerkt hast.

If you memorize "this melody at this pitch," you cannot adapt the moment the key changes. What you need is "relative pitch"—memorizing the relationship (intervals) between notes.

Scientific Background

Absolute Pitch vs. Relative Pitch

Absolute (perfect) pitch: The rare ability to identify pitches without external reference. Research suggests a critical period for acquisition, typically requiring early childhood exposure and training.

Relative pitch: The ability to perceive intervallic relationships from a reference pitch. Crucially, this skill is fully trainable at any age and is the foundation of professional musicianship.

For practical musicianship - including transposition, harmonization, and improvisation - relative pitch is actually more useful than absolute pitch. Musicians with strong relative pitch can perform fluently in any key, whereas those relying solely on absolute pitch often struggle with transposition.

Recommended Practice Method

Feature: Interval Recognition (Random Root Note Mode)

💡 Habit of Singing with "Movable Do"

Develop the habit of calling the tonic "Do" in any key. Whether in C major or G major, the first note is always "Do."

This allows you to recognize melodies as "positions within the scale" rather than "absolute pitches."

Can't memorize harmony parts

💡 Recommended Practice Method

Focus on training major 3rd, minor 3rd, and major 6th with Interval Recognition.

Learn to distinguish the most common interval relationships in harmonies. Once you master this, you can harmonize spontaneously.

Why This Practice Is Necessary

。Harmony means "singing at a constant interval from the main melody." Without understanding intervals, harmony is impossible.

Most harmonies are built on specific interval relationships like "3rd above," "3rd below," or "6th above." Understanding these relationships allows you to harmonize spontaneously while listening to the melody.

Problems This Practice Solves

Takes too long to memorize harmony parts
Get pulled toward the main vocal
Cannot harmonize spontaneously
Struggle with chorus work

Recommended Practice Method

Feature: Interval Recognition

💡 Start with "3rd Harmonies"

First, master distinguishing major 3rd from minor 3rd. Many pop harmonies are 3rd-based.

Once you can distinguish 3rds with Interval Recognition, practice singing "a 3rd above" while listening to your favorite songs. Start with simple melodies.
