Vocal Harmony: Complete Guide from Beginner to Advanced
Understand first, second and third vocal parts, thirds, intervals, soprano, alto, tenor and bass, and learn to build and sustain harmonies in practice.
Voice division is the act of singing different notes at the same time to form a harmony. The main melody continues to exist, but a second, third or fourth vocal line adds other notes that match the chords and the movement of the music. In this guide you will come out of the basic concept and reach the construction of harmonies in two, three and four voices.
1. First of all, melody, harmony and division are not the same thing.
Melody is the line we usually recognize as “music”. Harmony It's the set of notes that sound next to her. Vocal harmony is the distribution of these notes between singers or vocal lines.
If the melody sings the note C and the chord at that moment is C larger, a simple division can use E and G. The three C–E–G notes form the chord triad. This does not mean that every division needs to sing exactly the chord notes, but this is a safe basis for learning.
2. What's 1st, 2nd and 3rd voice
- First voice: It's usually the main melody.
- 2nd voice: an independent harmonic line, often built from Tuesdays, Fridays or chord notes.
- 3rd voice: adds another note to complete or enrich harmony.
These names describe functionNot necessarily height. The second voice may be above or below the melody. In an arrangement, “voice 2” does not always have to be the middle note.
3. Tuesday: the most used division — and why it changes
When someone says "it's a Tuesday," they're talking about a interval: the distance between two notes. In C major, C–E is a larger Tuesday; D–F is a smaller Tuesday. If you follow a diatonic scale “on Tuesdays”, the amount of semitones alternates according to the tonality.
Melody: C · D · E · F · G
Tuesday above the scale: E · F · G · A · B
The common error is to mechanically shift the voice by the same number of semitones. In practice, the division needs to respect the tone and, above all, the chord that is happening.
4. How to find a second voice without decorating the arrangement
- Discover the hue: know which notes belong to the main scale.
- Locate the chord of the moment: Ask what notes form this chord.
- See which note the melody already occupies: avoid simply duplicating it if you want to create harmonic opening.
- Choose a note next to the chord: for beginners, prefer smooth movement and comfortable region.
- Driving test: your line should sound like a candid phrase, not like random jumps between correct notes.
5. Parallel, opposite and oblique movement
A good division doesn't just live on parallel lines. There are three useful movements:
- Parallel: Both voices go up or down together.
- Contrary: One voice rises as the other descends.
- Oblique: One voice holds one note while the other moves.
Using the three moves makes the arrangement less predictable and helps prevent voices from crossing or becoming difficult to sing.
6. Soprano, contralto, tenor and bass: what this has to do with division
Soprano, high/contract, tenor and bass are names used for types or vocal parts in arrangements, especially in coral. They do not mean “third”, “second voice” or “third voice”. A soprano can sing the melody or a harmony; a tenor too.
In a SATB arrangement, for example, the chord can be distributed between soprano, alto, tenor and bass in different octaves. The goal is to keep each person in a comfortable fabric and create a smooth driving between the chords.
Do not classify your voice just by the most severe or sharper note you can issue. Vocal classification also considers tessitura comfortable, timbre and recording transitions.
7. Basic exercise in two voices
- Choose C4 as the main note.
- Listen to E4 as a bigger Tuesday above.
- Play C4 alone, then E4 alone and then the two notes together.
- Sing C4 while the reference touches E4.
- Switch: sing E4 while the reference plays C4.
- Repeat with D4–F4, E4–G4 and F4–A4.
The goal is not volume: to learn to recognize your note when another note is happening at the same time.
8. Intermediate exercise: do not follow the melody
The biggest challenge for those who begin to share is to abandon their grade when they hear someone else. Train like this: listen to the melody by two bars, enter your division and keep your attention in the contour of your own line. . Record the two lines separately and use one as a “virtual singer” to train against it.
If you fall into the melody, go back to the previous point and reduce the reference volume. Then slowly increase. Auditory independence is built gradually.
9. Harmony in three voices
In three voices, a common approach is to distribute the three notes of a triad. In C major: C, E and G. However, when the chords change, each singer does not have to jump to the next note “with the same function name”. Look for the nearest available note.
C major: C–E–G
F major: C–F–A
G major: B–D–G
C major: C–E–G
Note that some voices may repeat the same note between two chords. This is useful: less movement usually means more stability and tuning.
10. Advanced division: inversions, openings and stresses
When the group already holds well triads, you can try inversions (change which note stays in the grave), open voicings (remove notes by more than one octave) and tension notes, such as sevenths and ninths. The rule remains the same: each line needs to make sense alone and the set needs to serve the music.
Avoid adding tension just to look sophisticated. In congregational refrains or parts with dense lyrics, a simple division can communicate better than a harmony full of notes.
11. How to rehearse a group
- Teach every voice isol.
- Put two voices together before you put them all together.
- Use a neutral vowel first if the lyrics is disrupting the tuning.
- Then put the words and consonants back together.
- Record each line separately for home study.
- In the end, sing the full section without interrupting for corrections.
12. Four-week training plan
13. Errors that delay evolution
- Decorate only the note itself without understanding the chord.
- To confuse “contract” with “second voice” or “tenor” with “third voice”.
- Do everything on parallel Tuesdays even when the chord asks for another note.
- Sing the division stronger than the main melody.
- Choose correct notes in an uncomfortable region for the singer.
- Always train with all the voices together and never isolate the lines.
14. Use LETROU tools
On the page Tools for singers, use the Second-voice coach to hear intervals above and below, the Three-voice lab to isolate notes from a triad and the Independence training to practice without following the melody.
Today's Practice
Choose a simple song in known tone. In the chorus, identify the chord in each compass, write a second line with notes close to the chord and record first the melody, then the division. Only then sing your division against the recording of the melody.
Frequently Asked Questions
Second voice is always a Tuesday?
Oh, no. Tuesday is widely used, but the second voice can use Friday, Wednesday, Thursday, sustained note, passage or other note suitable for chord and driving.
Contralto is the second voice?
Not necessarily. Contralto/alto describes a region or vocal part; “second voice” describes a function in the arrangement.
Is it better to split up or down?
It depends on the melody, the chord, and the music of the singers. The best choice is the one that sounds musical and remains comfortable.
How do you stop falling into the main melody?
Train your isolated line, then against a low-volume melody recording and gradually increase the reference.
