There are a number of exercises you can do to help develop your vocal cords and to help you improve your singing voice or warm it up for use. Here are some vocal exercises you can try:

1. Try to sing a single note and then hold that note or go on for as long as possible without getting out of breath.

2. Do the previous exercise of singing a single note again but instead of singing one note, try it this time with the whole scale do, re, mi, fa, so, la, ti, do one at a time.

3. Sing the same exercise only this time, instead of using the doremi scale, use the vowels. This will help you improve the way you open your mouth and emphasize your vowels as you sing.

4. Another exercise that you can use to prepare to sing is to recite the full vowel in one note.

5. One of the most effective and well-known ways to train your voice is by practicing scales. You can practice scales by first finding out what your range is. The range can be anything from tenor to soprano. Once you know your range, use a piano or keyboard and move up and down the doremi scale with a vowel sound, slowly increasing the pitch after each step.

6. When you do scales, try to do it in short notes or staccato and with the use of long notes as well.

7. You may think tongue twisters are childish or silly, but these silly rhymes can help you improve your singing. Use tongue twisters to help loosen your tongue and vocal cords.

8. An alternative to the usual scale of one vowel or sound is one in which you use “yo, mayo, mi, moo, moo” on one note, and then slowly move up the scale with this same set of sounds. The next thing you’ll need to do is change the “m” in the set with another consonant after three tries.

9. One of the important things to do when vocalizing is to do breathing exercises. Breathing incorrectly won’t help improve your voice, so you’ll also need to learn proper breathing exercises and techniques. A breathing exercise you can use teaches you how to use your diaphragm. Just say “shh” with your finger over your lip and breathe out like this until you’re out of breath. Do this a few times.

10. Another breathing exercise that can help you with your singing or can be done in conjunction with other vocal exercises involves breathing in for 20 seconds and breathing out for 20 seconds after reaching the 20 second mark for inhalation.
