Fun time. We're going to take an old (slow) spiritual and surprise some people!
|

We'll also learn about repeats, play with volumes, and do some interesting

tempo things.

We want to surprise our listeners a bit, so we start off with a ``normal''

tempo. The single ``z'' produces a 4 beat introduction.

Surprise time. We are going to pump the tempo up to 140 BPM and

select the Swing2 Groove.

If we just did a switch of rhythm and tempo it'd be quite ``interesting''.
|
|
We need some
|
|
kind of a transition. Hmmm, what if we have two beats (not four) of swing
|
|
drums? We could create a 2 beat measure, but it's quite cool to give the
|
|
drummer a real workout. So, here we double the time and put in a single
|
|
``z'' bar.

Each time we restart the piece we want the same volume setting. This is bit
|
|
of overkill, but it's supposed to be an example. So, we set the volume to
|
|
``mf'' and assign that to the <B>Volume Groove</B> ``Main''.

The ``Swing2End'' groove has a neat little saxophone scale. But only on the
|
|
third and fourth bars. It is a four bar sequence and the first two give
|
|
the sax player time to rest. The <B>Seq 3</B> forces the sequence to use
|
|
the bar with the solo. We also set the solo to a louder volume.

Compile this example and play it. Follow along on both the sheet music and the

Certainly, the ideas here only scratch the surface of what

We, as developers, can only hope that we've included enough commands and options

for you to create wonderful music. And hope that if we haven't, that you

let us know.
