Lead singers get a lot of attention, but they are rarely the only singers in a band. Backup vocalists give depth and richness to the song by harmonizing with the lead singer. Some songs were meant to be sung completely in harmony.
If you're having trouble harmonizing, there are some steps you can consider to mix your voice with others:
Start with the Basics
Before you learn to sing with others, you must learn to sing on your own. Start by learning to sing the C chromatic range. You will quickly learn to identify your natural vocal range and expand it.
Breath control is one more essential part of singing. Learn to breathe deeply in a way that fills your lungs and makes your stomach enlarge when you inhale. You can even increase your lung capacity by drawing deep breaths and holding them for significantly longer periods of time.
Learn to Match Pitch
Next, play a scale on a piano or use a virtual tuner to play notes. Sing along with each note and try to match your pitch to the note. This is a vital lesson for anyone who desires to sing harmony.
With some exercise, you will learn to recognize proper pitch by ear and understand when you're on pitch or off. Keep your vocal chords warmed up and relaxed to avoid tensing up and throwing off your pitch.
Practice All the Parts
When you're getting ready to harmonize with other singers, it helps to know their parts as well as your own. Practice singing the lead vocals and the various parts of the harmony. When you know how the other singers will sound, you can take steps to match your voice to theirs.
Learn to use right enunciation and to inhale without whispering. You want your voice to mix smoothly with the other vocalists, so avoid harsh or sibilant sounds by simply skipping complex letters, like 's'.
Strive for Balance
When harmonizing, you don't need to stand out from the audience. Control your volume to keep it on par with the other singers. Don't add elements of your own stylistic tones or over sing your part, because it will only take away from the harmony.
Keep in mind, you and the other harmonizers are a team. Your voices should blend to form a complex but stunning sound, with no individual voice grabbing more than its share of attention.
Record Your Practices
Many vocalists like to record their practice sessions and play them back to hear for problem areas. Record yourself as you attempt to accommodate with musical notes and other people's voices.
Practice often, and continue to record and play back your sessions. After a week or so, you will hear an improvement. Harmonizing will come easier, and it will feel more natural.
Train Your Ear
When people harmonize in perfect pitch, their voices resonate with each other. Try to match your pitch and volume to someone else voice and you will hear this effect. It happens when voices blend perfectly.
You can prepare yourself to listen for this resonance, and to listen for argumentation that suggests aggravated harmonizing. It takes practice, but getting able to harmonize by ear is very nice reward for your efforts.
Get an Audio Training Course
Many singers need someone to help them learn harmony. There is no shame in seeking the guidance of a professional voice coach, though the cost of private lessons can be prohibitive.
