If you're learning a new song, try singing it without the consonants. This can have a variety of positive effects.
1. It makes plain the connections between vowels that you need for legato singing.
2. It will reveal any technical problems before they become embedded in your practice of the song.
3. It can illustrate where you will need to breathe in a line, or help you plan your breathing so that you don't break a phrase in an undesirable location.
4. It will show you how your voice sounds without the airflow interruptions that consonants create, giving you an idea of what to work towards as you re-integrate the consonants.
For particularly challenging songs, you might even begin using only the lip trill, or a solid vowel sound instead of the vowels from the lyrics.
