How could we attempt to have the same tempo, and different time signature then? Like the following example:

Example 4.4

Here both instruments move at the same tempo, but have different time signatures, thus the barlines are in different places!

Now, the problem in Finale, lies that the minute you change the time signature, you effectively change the tempo as well (as shown in example 4.2).

There are 2 ways to counter that!

i. Don't change the time signature. This can be done in two ways:

Go the the [i]time signature tool ->options[i]. On the lower window, which just appeared, check the [i]use a different time signature for display[i]. And choose 3/4, there, while leaving intact the true time signature above.

This will display a 3/4 on the above staff, but in reality it will count 4/4. Just erase the barlines (as mentioned bellow example 4.1) and draw your own.

ii. Change the time signature, but make truplets, or any other combination to reach the needed tempo.

While the first method is tons easier, still this method will come in handy, so I'm mentioning it now.

Go to the [i]time signature tool[i] and click on the bar. Change the time signature from 4/4 to 3/4. That will screw up your notes and length of the notes, so better wait to input the notes, after you've done this change.

Then.

Pick the tuplet tool, or in speedy entry ctrl+1 (which brings the tuplet definition window). Make all notes into 4:3 (or 4/3) ratio. This means that every 4 notes, fit in the space of 3 notes. A normal triplet, is actually 3:2 (3/2), which means that 3 notes fit in the space of 2!

In the example 4.4, the first 4:3 grouping, has on the appearance number: ratio, or X/Y, and on the shape: bracket. Second grouping has on the appearance number: number and on the shape: bracket. Third grouping has on number: nothing, and on shape: bracket. The last grouping has on both choices: nothing!

Draw the barlines, and you're done!

(The sign at the end of the staff, means that the bar continues to the next system, or line. This was done with the legato tool, as described on the glissando part of the tutorial.


Example 4.5

Example 4.5 features the same time signature, but different tempo.

As you can see, the method is not vastly different really...

just notice that 75/60=5/4, which is the ratio used in the tuplet definition.

finally


Example 4.6

Here is the combination of 2 different techniques.

The idea is to find the right ratio!

since the tempo is 75 and 60, the same ratio, should apply 5/4, but in this instance, the time signature, is 3/4 in the above staff, so the ratio needs to be 5/3.

Go figure...

More complicated rhythms and tempos are a big mess really...

But this is the way to go, generally.

notes: Playback is affected, but the accents are not. It takes plenty of tweaking to make it sound right!

Also keep in mind that Finale does not particularly enjoy ratios of the following sort: 5.6/3.4... Find full numbers to use, no matter how high... The example there would be 28/17...

See it's turning damn difficult again? Not so much from the Finale point of view, but for the maths involved and the brain twist!
