OK…
Exercises can be helpful.
They help you work on certain issues…
If you working on falsetto…
Well then create an exercise to help you get to it.
That can work…
The big problem though with exercises like that..is that they remove context…
What do you mean?
I mean you have a hard time implementing those “runs” into your singing without them sounding like exercises.
Listen to some artists and it sounds like they are doing an exercise.
However…Lets say you need to work on falsetto…
Go find a riff from Brian Mcknight or Boys 2 Men or etc…
And practice it as an exercise…
Now…when you get it…you are working on your falsetto…but you are also learning a riff that doesn’t sound like an exercise and you have already heard it in context…
You can put it in your singing…
So yes you must do exercises…but why not create an exercise out of a REAL riff…
That’s what I am doing right now with Sam Cooke and the song Wonderful…
