The 90-Minute Plan
Harmony usually uses thirds or fifths above the melody. Play a note on an instrument, then sing a note a third (4 semitones) above it. Sing it 20 times to internalize the sound. Do this for melody notes in your song.
Write out the melody notes. For each, identify the harmony note (usually a third above). Test each on an instrument if possible. Create a simple sheet or list. This takes thinking but removes live improvisation.
Play the backing track softly. Sing the harmony line slowly while tracking the melody in your head. Record this attempt. Listen back. You're building the ear-voice connection.
If with a partner: one sings melody, one sings harmony. Hold the harmony note steady even if theirs wavers. If alone: record melody, play back, sing harmony over it.
Focus on matching your partner's volume and timbre. The goal is that both parts sound like they belong together. Do 3 complete passes. By the third, it should feel organic.
Harmony is hardest when you can hear the melody—many singers naturally pull toward the melody instead of the harmony. Think 'support' not 'separate'.
