Core pages

  • Home HengHeng is a browser-based vocal-training toolkit. See your pitch, breath, and resonance in real time and turn dull warm-ups into playful, visual games. Free, no install, works on phone and desktop.
  • Features Do not try every tool at once. Decide whether today is about pitch, breath, resonance, vibrato, or listening, then open the matching tool for a short 3 to 10 minute drill. HengHeng works best as a loop: set a target, sing, read feedback, fix one thing, repeat.
  • Guides Find singing guides by practice problem
  • Learning paths Follow ordered practice journeys
  • Glossary Understand pitch, breath, resonance, and related terms
  • Resources Checklists, logs, and tool-selection guides
  • Download
  • FAQ Product, practice, safety, and platform questions

Singing guides

  • How to sing in tune Singing out of tune is usually not a broken voice. It is a missing loop between reference pitch, listening, and vocal control. Use a piano target, verify with pitch tracking, then build stability through ear training and games.
  • 10-minute warm-up A warm-up is not about singing louder. It is a gradual setup for breath, vocal-fold coordination, resonance, and pitch accuracy, starting light, short, and low-risk.
  • Breath support Breath issues often show up as running out of air, falling endings, wobble, or a squeezed tone. Start by stabilizing short sustained notes before extending phrases.
  • High notes High notes are not built by forcing harder. First find the highest note you can control today, then expand gradually by semitone or small interval steps.
  • Clearer tone A muffled tone often relates to mouth space, vowel shape, breath stability, and resonance strategy. The goal is not to shout brighter, but to find an easier clear tone.
  • Vibrato practice Vibrato is not just shaking the voice. First sustain a stable tone, then observe whether width and rate are even, and finally place it at phrase endings.
  • Practice a song When practicing a song, do not only sing it from top to bottom. First check whether the range fits, then isolate hard phrases, endings, breaths, and tone.
  • Cents deviation Cents measure distance between pitches. In 12-tone equal temperament, one semitone is 100 cents and one octave is 1200 cents. For singers, cents deviation shows whether you are sharp, flat, or falling at the end.
  • Choose a song key The original key may not fit your voice. To choose a key, first test the low notes, high notes, and longest phrases that tend to cause trouble, then decide whether to transpose up or down.
  • Ear training for singers Ear training is not only for music students. For singers, the practical goal is to hear a note, short phrase, or interval and reproduce it accurately.
  • Karaoke pitch practice In karaoke, common pitch problems are drifting flat with the backing track, missing chorus notes, and unstable endings. Practice away from the backing track first and turn hard phrases into short loops.
  • Online vocal tools Online vocal tools do not replace a teacher. They make self-practice visible through reference notes, pitch curves, breath stability, resonance, and vibrato records.
  • Falling endings Falling endings can make an otherwise good phrase sound unsupported. They usually involve airflow release, target memory, and attention at the end of the phrase.
  • Tight high notes Throat tension on high notes often means the target is beyond today's controllable edge, or you are squeezing for pitch and volume. Lower the note first, then check breath and tone.
  • Daily practice routine Daily vocal practice does not need to be long, but it needs a clear order: warm up lightly, train one core skill, then apply it to one phrase.
  • Chorus high notes Chorus high notes are not only about the high note itself. Entry pitch, the previous breath, volume change, and ending all affect stability.

Learning paths

  • Beginner pitch path For beginners who sing off pitch or cannot tell whether they are in tune. Build a reference, read the pitch curve, then stabilize short phrases.
  • Karaoke pitch path For singers who are okay a cappella but drift with accompaniment. Focus on key choice, entry notes, and endings instead of full run-throughs.
  • High-note path For singers who get tight, crack, or shout on high notes. Find today's controllable top first, then extend gradually.
  • Daily 10-minute path For singers who want a habit but do not know what to practice. Keep one focus, record the result, and continue next time.

Vocal glossary

  • What are cents? A cent is a unit for pitch distance. In 12-tone equal temperament, one semitone is 100 cents and one octave is 1200 cents; it makes pitch deviation measurable.
  • What is pitch? Pitch is the perceived highness or lowness of a sound, commonly related to fundamental frequency. In singing, the goal is stable, repeatable control near a target note.
  • What is breath support? Breath support is not simply inhaling more. It is stable, controlled airflow during phonation, affecting sustain, phrases, endings, and tone stability.
  • What is resonance? Resonance is how vocal sound is shaped by spaces such as the mouth and pharynx. Practice is about space, vowels, and airflow, not squeezing for brightness.
  • What is vibrato? Vibrato is periodic pitch motion on a sustained tone. Natural vibrato tends to have even width and rate; unstable straight tone usually leads to messy vibrato.
  • What is vocal range? Vocal range is the span of pitches a person can produce, but practice depends more on controllable range: repeatable, stable, and not throat-tight.

Practice resources

  • Content methodology How HengHeng chooses topics, cites sources, turns concepts into drills, handles voice-safety boundaries, and links every guide to usable tools.
  • Singing problem checklist Break common singing problems into observable signs: off pitch, falling endings, short breath, muffled tone, and high-note tension. Diagnose before choosing a drill.
  • Pitch practice log A daily 5-10 minute pitch-practice template for target notes, sharp/flat tendency, falling endings, and the next phrase to fix.
  • Karaoke phrase worksheet Break a song into entry notes, longest phrases, chorus high notes, and endings. Useful when accompaniment makes pitch drift.
  • Online vocal tool guide A selection guide for online piano, pitch monitoring, breath stability, resonance feedback, and vibrato analysis. Pick by problem, not by opening everything.
