Having trouble muspy.metrics

[hyeshinchu]

Hi,

I have a question about using muspy.metrics.
I'm trying to check pitch_range using the metrics, but having an AttirbuteError.

I defined the music I want to check,

music1 = ('./unconditional_4.mid')

and typed the line as below,

muspy.pitch_range(music1)

but I got an error message.

AttributeError: 'str' object has no attribute 'tracks'

AttributeError Traceback (most recent call last)
/tmp/ipykernel_3330136/2725394534.py in
----> 1 muspy.pitch_range(music1)

~/.conda/envs/muspy/lib/python3.8/site-packages/muspy/metrics/metrics.py in pitch_range(music)
91
92 """
---> 93 if not music.tracks:
94 return 0
95 if not any(len(track.notes) > 0 for track in music.tracks):

AttributeError: 'str' object has no attribute 'tracks'

Any advice would be appreciated!
Thank you.

Hi @hyeshinchu,

You need to read the MIDI file into a MusPy Music object first.

import muspy
music = muspy.read("./unconditional_4.mid")
print(muspy.pitch_range(music))

Let me know if you have any other questions. Thanks!

Hi @salu133445 ,

Thanks for the prompt and clear answer!
Now I can check the value for all metrics.

And I want to express my thanks for the amazing Muspy :)

Thank you.
