# Note length line (beam) placement in numbered musical notation

I am making a computer application for typing numerical / numbered musical notes. I have some question regarding note length line / beam.

1. Will it have a same meaning if we place the beam either on top of the note or on the bottom?
2. If #1 = yes : In a scores sheet, is it normal to use both of the placement (some part use top beam, some part use bottom beam)? Or is it better to use only 1 rule per scores sheet? (I assume the latter)

Example of scores with bottom note beam (source : http://en.wikipedia.org/wiki/Numbered_musical_notation) :

UPDATE : Top note beam example (source : syaifulcamp.blogspot.com) :

Ugh, I just realized, is top beam is only used in indonesia? :/

Why would you use that notation? Nobody will know it and it's not even something you can do with straight text. What does it offer that beats standard notation? – Stephen Hazel Jun 12 '14 at 16:17
@StephenHazel actually the wikipedia article explains why. – Roland Bouman Jun 12 '14 at 16:40
I am making apps for use in indonesia, which still widely use numbered musical notation along with the standard one. So, the answer is? – Moses Aprico Jun 12 '14 at 19:01
Sorry, I'm not entirely understanding the question. The Wikipedia page makes it sound like the "beams" are always beneath and I can't find any reference to beams above the numbers. Are you asking about how beams work in traditional western notation? – Pat Muchmore Jun 12 '14 at 21:25
I'll leave it to someone more familiar with the actual notation to provide an official answer (if anyone that knows sees it), but I see no way it could possibly make any rhythmic difference. The basic unit is the quarter note, and all one needs are ways to make notes shorter or longer. As I understand it, longer notes are indicated with lines after the note, shorter notes are indicated by lines below the notes. I can't think of a third option that could be the meaning of lines above, so I assume it's just a variation. Beam direction doesn't have a rhythmic meaning in Western notation either. – Pat Muchmore Jun 13 '14 at 16:30
