Second voice in thirds in B major
In B major, a second voice in thirds sings, above each note of the scale, the note of the key two steps higher: B–D♯, C♯–E, D♯–F♯, E–G♯, F♯–A♯, G♯–B, A♯–C♯. The third is major above B, E, and F♯ and minor above C♯, D♯, G♯, and A♯.
The B major scale with the second voice
Each row is a degree of the B major scale: the melody note, the second-voice note and the interval between them.
| Degree | 1st voice (melody) | 2nd voice: third above | Interval |
|---|---|---|---|
| I | B | D♯ | major third |
| II | C♯ | E | minor third |
| III | D♯ | F♯ | minor third |
| IV | E | G♯ | major third |
| V | F♯ | A♯ | major third |
| VI | G♯ | B | minor third |
| VII | A♯ | C♯ | minor third |
On the staff
The B major scale going up, with the second voice on the lower staff. The numbers between the staves are the intervals (3 = third, 6 = sixth).
Hear it and practise in B major
The tool below opens with Ein feste Burg ist unser Gott, transposed from C major to B major, and the second voice in this style. Change the melody, the style and the key whenever you like.
1. The melody
Melody only: no lyrics.
Type C D E F G A B (or do re mi fa sol la si), # and b for sharp and flat, :2 for 2 beats, :1/2 for half a beat, p for a rest. Without a number, each note goes to the octave closest to the previous one; ' raises it an octave and , lowers it.
Length
Turn it on, wait for a one-bar count-in and sing (or play) the melody in time with the click. Nothing is recorded: the device only writes down the notes.
2. The second voice
Style
Transpose · Range of whoever sings the 1st voice · Chords
E.g. C | G7 | C F | G C. In the choir style, the 2nd voice prefers chord notes on the strong beats.
3. See
Choose, type or sing a melody to start.
The numbers between the staves are the intervals (3 = third, 6 = sixth, 8 = octave). Tap a note in the 1st voice to fix it.
Tab for both guitars and the positions on the fretboard: filled = 1st voice, ring = 2nd voice. The guitar sounds an octave lower than written.
Each staff is written the way the player reads it (already transposed for the instrument). In red: outside the comfortable range.
4. Listen
5. Practise
The app plays one voice and you sing or play the other. Each note lights up green (right), yellow (close) or red. Nothing of your voice is recorded: only the score stays on the device.

Listening
Without headphones, the other voice plays quietly and the microphone ignores anything that matches it. Sing much louder than the phone (or use headphones: it works much better).

To find the third above, count two notes up the B major scale: from B, skip C♯ and land on D♯. Because the count stays within the key, both voices always sing notes of B major, and the size of the third changes with the degree: a major third is 4 semitones and a minor third is 3.
In B major, the major thirds fall on degrees I, IV, and V and the minor ones on degrees II, III, VI, and VII. That is why the second voice is not the melody copied a little higher: it follows the same shape but alternates major and minor thirds to stay in the key.
If the third above gets too high for whoever sings the second voice, sing the sixth below: the same note, an octave lower. It is what Brazilian country duos do when the melody climbs.
