Posture and relaxation
Your body is the instrument. Stand with feet about shoulder-width apart, weight on both feet, knees soft (not locked), back tall, shoulders relaxed and down, chin level. If you sit, sit on the front of the chair with both feet flat.
Tension in the jaw, neck or shoulders squeezes the voice. Before singing, roll the shoulders, yawn gently, massage the jaw, and take three slow breaths to calm the mind. A calm, focused body sings more freely and remembers words better.
Breathing and breath control
Singers breathe low. The diaphragm, a dome-shaped muscle under the lungs, moves down when you breathe in, so the lungs fill and the belly and lower ribs move out. The shoulders should not rise.
Breathing out is controlled: let the air out slowly and evenly so a long phrase does not run out of breath. Practice:
- Breathe in for 4 counts, hiss "sss" out for 8, then 12, then 16 counts.
- Pant like a puppy to feel the belly muscles work.
- Mark breath points in your song (usually at commas or ends of lines) so you never break a word.
How the voice makes sound: pitch, range and voice types
In your throat, inside the voice box (larynx), are two small folds of tissue called the vocal folds. Air from the lungs makes them vibrate, and the vibration sets the air moving as a sound wave. The sound then gets louder and richer in the spaces of the throat, mouth and nose (resonance).
Pitch depends on how many times per second the folds vibrate (frequency, in hertz, Hz). The A above middle C is 440 Hz. Tighter, thinner folds vibrate faster and give higher notes.
The range is the span of notes you can sing comfortably. Common voice types, from high to low: soprano (about 260–1050 Hz), alto (about 175–700 Hz), tenor (about 130–520 Hz), bass (about 80–330 Hz). Boys' voices drop during the teenage years as the folds grow longer and thicker; sing gently and in a comfortable range during this change.
Diction, expression and warm-ups
Vowels carry the tone: keep them open and long ("ah", "eh", "ee", "oh", "oo"). Consonants carry the meaning: make them short and crisp, especially at the ends of words.
Expression: follow the dynamics (soft p, loud f, getting louder crescendo), shape each phrase towards its most important word, and show the mood of the text with your face.
A 5-minute warm-up: body stretch → breathing → lip trills or humming → sirens from low to high → simple five-note scales on vowels → tongue-twisters for diction. Look after your voice: drink water, rest it when hoarse, and never shout or force high notes.
Singing in a choir: parts, harmony, tuning and conducting
A mixed choir usually has four parts, SATB: soprano, alto, tenor, bass. School choirs often sing in unison (everyone the same tune), then in rounds or canons, then in two or three parts. When the parts sing different notes that fit, you hear harmony.
Tuning: two voices on the same note are in tune when their vibrations match; if one is slightly off, you hear a wobble (beats). Listen more than you sing, match the voice next to you, and blend so no single voice sticks out.
Conductor's gestures: the preparation breath (raised hands, everyone breathes in together), the beat pattern (down-up for 2, down-out-up for 3, down-in-out-up for 4), cut-off (a small circle closing), and hand height or size for loud and soft.
Choirs sing many kinds of music: folk songs, songs from many countries, sacred music and pop arrangements. In India, group singing of patriotic songs and bhajans follows the same rules of blend and breath.

Worked examples
1. A note is 220 Hz. What is the note one octave higher?
One octave up doubles the frequency: 220 × 2 = 440 Hz.
2. Your phrase is 12 beats long and you keep running out of breath at beat 9. Give two fixes.
1) Breathe low and slowly before the phrase, and let the air out evenly (practise hissing for 12 counts). 2) Mark a quick catch-breath at a natural comma if the words allow it.
3. A choir of 24 has to sing SATB. Suggest a balanced split.
Six per part is simplest: 6 S, 6 A, 6 T, 6 B. If the low voices are weak, move to 6 S, 5 A, 6 T, 7 B so the bass supports the harmony.
4. Plan a 5-minute warm-up for a class before assembly.
1 min shoulder rolls and stretches; 1 min breathing (4 in, 8 out on sss); 1 min lip trills and sirens; 1 min five-note scale on "mah-meh-mee-moh-moo"; 1 min tongue-twister and first line of the song.
Common mistakes
- Lifting the shoulders when breathing in; the breath should go low, belly and ribs out.
- Pushing loud high notes from the throat; use breath support and resonance instead of force.
- Singing louder than the rest of the choir; in a choir you listen and blend.
- Swallowing the end consonants, so the audience cannot understand the words.
