Country duo second voice in F major

In F major, a Brazilian country duo (sertanejo) usually sings the second voice in thirds above the melody (F–A, G–B♭, A–C, B♭–D, C–E, D–F, E–G) and, when the third gets too high, drops to the sixth below: the same note, an octave lower.

The F major scale with the second voice

Each row is a degree of the F major scale: the melody note, the second-voice note and the interval between them.

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.

Strictness

The table shows the two notes the second voice can sing on each degree of F major: the third above, the way duos do it, and the sixth below, which has the same name and sits an octave lower. The second voice stays on the third while it fits the voice and moves to the sixth when the melody climbs too high.

It is best to switch rarely and, preferably, after a rest or a long note, so the switch does not show in the middle of a phrase. In the tool, the “Country duo (sertanejo)” style picks those places by looking at the whole song, within the range of whoever sings the second voice.

Frequently asked questions

How do you sing a country-duo second voice in F major?

Sing the third above each melody note (F–A, G–B♭, A–C, B♭–D, C–E, D–F, E–G) and, when it gets too high, the sixth below, which is the same note an octave lower. Go back to the third as soon as you can.

When does the second voice switch from the third to the sixth?

When the third above would go beyond the range of whoever sings the second voice. The switch sounds best after a rest or a long note, and the fewer switches, the more natural it sounds.

Does the duo’s second voice go above or below the melody?

Usually above, in thirds. The tool’s “Country duo (sertanejo)” style also does the opposite: a third below that becomes a sixth above when the voice goes too low.
