Can I create a three-quarter note with Tunescope? Or must I specify a half tone followed by a quarter note? (It sounds differently)
Also, I found that the Tunescope Reference (as referred to in the Snap! Reference Manual) is very confusing as to how to create a Measure or Section (it suggests compiling elements in a list, whereas the blocks actually take variadic input).
You can use numbers as durations, but for some reason they decided to make them seconds, so you can't just type 3. However, you can use tmy unescope modification, which uses the same durations as the primitive play note block.
Another question regarding Tunescope: I have been trying to create a track with both chords and single notes. My assumption is that this would need to be a “chord” track, with single notes styled as chords (i.e. as a single-element list), is that correct?
Example (the first two measures of a famous classical harpsichord piece; its left-hand part (the second track) has mostly single notes and a few chords):
What it does is replace any single note within a sequence with a chord consisting of the note and two R’s (= rest); the pre-existing chords are left as they are.
I’m not even sure if the two R’s are required. A list with the note as single element appears to work as well - but since chords are defined as having a three elements or more, I added them anyway, “just in case”.
Another useful TuneScope extension block
Suppose your music score consists of many measures, and you need to add a track consisting of just one small part, like a few trumpet blows during the last seconds. You can use the following block to insert R’s during the preceding measures:
The standard music notation way to do that would be to use a tie: a half and an eighth note with a ⁀ spanning both of them. I don't know if Tunescope has a notation for that.
But there's a limit to how far you can take such questions. There's no notation, afaik, for a seventh note in our standard music representation. Other cultures have other notations, and also, weird modern musicians who want things like seventh notes make up their own notations.
It doesn't, but it does allow you to enter numbers as durations... in seconds. I really don't like this because music doesn't use seconds for time, it uses beats per second minute, and snap (and scratch) already has a play note block that uses a note duration, which is not the same as tunescope. In order to get note durations that use beats instead of seconds in tunescope (for doing stuff like making ties), you need to do some math (or just edit the block to remove the seconds conversion). Of course you do need to do math for the play tracks block, because the seconds conversion is done in javascript.
No, no, it's plain "beats," not per anything. The context was "music doesn't use seconds for time, it uses ___" and the unit of time is the beat. "Beats per second" (or per minute) is the unit of tempo: how long in actual time is a unit of music time. (EDIT: Well, okay, the unit of tempo is actually the reciprocal of that, seconds per beat.)
Well, anyway … @ego-lay_atman-bay has a point: it’s somewhat inconvenient that Tunescope (being its authorized music library) doesn’t fully support Snap!’s tempo system (though I’m not sure what it does with numbers for notes - especially with very low tempi, below 20). Perhaps that’s another thing @glenbull (and you?) could look into during college break.
