TimeSignature

Overview

TimeSignature is a class to to fetch time signature info from a Scopul object. It has 4 properties: ratio, count, denominator, numerator, and one method: list().

Here’s an example of how to fetch a TimeSignature object of a Scopul object:

from Scopul import Scopul

scop = Scopul("test.mid")
time_signature = scop.time_sig_list[0]
print(time_signature)

# Sample output
>>> <TimeSignature.TimeSignature object at 0x0000029C5E1A5610>

Creating a TimeSignature object

TimeSignature(self, value: str, measure=None)

You can create your own note class, which you may use to append to the existing MIDI or use for other purposes

Args

• value : the time signature as a string
  • Ex. "6/8", which is middle C
• measure: The measure number of the Time Signature

To make create a Tempo class:

from Scopul import TimeSignature

my_note = TimeSIgnture(value="4/4", measure=28)

Properties

• ratio
  • Fetches the time signature as you would normally see it on sheet music
  • Returns
    • A string, Ex: 3/4
  • Example

      from Scopul import Scopul
    
      scop = Scopul("test.mid")
      time_signature = scop.time_sig_list[0]
      print(time_signature.ratio)
    
      # Sample output
      >>> "6/8"
    

    
    

• denominator
  • Fetches the denominator of the time signature
  • Returns
    • An int, EX: 4
  • Example

      from Scopul import Scopul
    
      scop = Scopul("test.mid")
      time_signature = scop.time_sig_list[0]
      print(time_signature.denominator)
    
      # Sample output
      >>> 4
    

    
    

• numerator
  • Fetches the numerator of the time signature
  • Returns
    • An int, EX: 4
  • Example

      from Scopul import Scopul
    
      scop = Scopul("test.mid")
      time_signature = scop.time_sig_list[0]
      print(time_signature.numerator)
    
      # Sample output
      >>> 2    
    

    
    

• measure
  • Gets the measure in which this time signature appeared in
  • Returns
    • an int, representing the measure number. For example: 5
  • Example

      from Scopul import Scopul
    
      scop = Scopul("test.mid")
    
      # Getting list of tempos
      signature_list = scop.time_sig_list 
      rendom_signature = tempo_list[0] # Sample index
    
      print(random_signature.measure)
    
      # Sample output
      >>> 1
    

    
    

• music21

  • the music21 property returns the Music21 Object for the Time Signature object

  • Example

    from music21 import note
    from Scopul import Scopul, TimeSignature
    
    signature = TimeSignature(value="3/4")
    print(signature.music21)
    
    # Sample output
    >>> <music21.meter.TimeSignature 3/4>00>
