Hi. It is possible to create nested tuplets simply by appending additional 'Tuplet' objects to a duration. Unfortunately, however, these will not display accurately in Musescore or Finale (they will render in midi).

I'm really glad you have enjoyed my videos. I understand why the official documentation may seem a bit daunting. Music21 is packed with features (possibly a bit bloated in places), so beyond the basics, you may find some of these are redundant. I don't know of any other resources specifically about Music21 but I think the best way forward is to experiment.

I'm glad they are helpful.

Thank you; this is really encouraging! I'm very happy you found my content and have enjoyed it.

Converting an audio recording to notation is still a challenging task and so unfortunately it isn't possible to apply chordify to audio files, such as MP3 and WAV. You can use chordify with MIDI files.

I have the same problem

Hi. I can't answer definitively but I believe so. The corpus is freely distributable but it may also depend on where you are located.

Thank you. I'm glad you're enjoying it.

I'm glad you enjoyed it. You can take a few different approaches to create chords or chord progressions with random walks. One way, for example, is to apply random walks to create separate voices before combining them to make chords. Another way is to use a random walk to move through a list of chords.

Hi. Parsing mp3 files into music notation would be very difficult and unfortunately, it's not possible to do this in Music21.

@@codemeowstro1701 Thx. WIll try Spleeter then. And see what i can do with that.

Thank you, I'm glad you've enjoyed it. Just intonation is indeed derived from the harmonic series.

Thank you, I really do appreciate the feedback. I'm quite new to UA-cam so hopefully, my delivery and pacing will improve as I make more videos. I'm not an author of Music21; I'm a musician with a particular interest in computer-aided composition and have found it to be an especially valuable tool.

@@codemeowstro1701 I would describe myself the same way. What are the odds two musicians with a particular interest in computer aided composition might find themselves here 🤔 Would you be interesting in sharing more of what you're working on? I'm very curious, I've never really spoken to someone else with this specific intersection of interests

Thanks for your comment. I agree that the best use of music21 itself is likely not to generate entire scores from scratch but as a tool to enrich specific aspects of the compositional process. If you intend to use Music21 and Python to manipulate scores that you have generated in notation software, including Musescore, Sibelius, Finle and Dorico, the best approach is to export your work as a MusicXML file, this can then easily be loaded into Music21 using converter.parse(). I recommend watching my video, 'How To Work With The Corpus And Your Own Files In Music21', which shows how to do this. I'm also open to making a more in-depth video specifically focused on importing and exporting files if this would be helpful.

Hi, which system do you mean?

Thank you! Your comment is truly appreciated and I am encouraged. I will certainly continue to upload.

Hi, This is due to how music21's chord representation works. The music21 library uses a chord.tables module to determine chord names. Unfortunately, this module does not include suspended chords within its database. It would be possible to extend the library's behaviour or write your own function to do this. Your code sample already specifies the root as C4; you can confirm this by printing stack.root().

Thank you, I'm delighted to hear that!

Hi. I'm not using a UI in this program; only vscode. Perhaps you're referring to the notation? If you have Finale, Sibelius or Musescore installed, you can use .show() to view a notated version of a Music21 object.

This sounds like an interesting project. Whilst I don't think this can be done in Music21 alone, it should certainly be possible in Python. I suggest having a look at PyGame for real-time midi playback.

I'm glad you're finding this helpful. Regarding your question, there are a number of features that enable pitch class set analysis. Many of these are methods of the Chord class, such as forteClass(), intervalVector(), normalOrder() and getZRelation().

from music21 import converter, instrument, note, stream def tab_to_sheet(tab): # Create a new stream to hold the sheet music sheet_music = stream.Stream() # Set the instrument to guitar guitar = instrument.Guitar() sheet_music.insert(0, guitar) # Split the tab into individual lines lines = tab.split(' ') for line in lines: # Remove whitespace and empty lines line = line.strip() if not line: continue # Split the line into individual notes or chords notes = line.split('-') for n in notes: # Check if the note is a chord if 'x' in n: # Create a chord object chord_notes = [note.Rest()] # Placeholder for rest chord_duration = 0 # Iterate through each character and create individual notes for c in n: if c.isdigit(): fret = int(c) note_obj = note.Note() note_obj.pitch.midi = 40 + fret # Assuming standard guitar tuning chord_notes.append(note_obj) elif c == 'x': chord_notes.append(note.Rest()) else: # Handle other symbols like hammer-ons, slides, etc. pass # Determine the duration of the chord (e.g., by counting dashes) chord_duration = len(5) # Customize this based on your tab notation # Create the chord and set the duration chord = chord_notes chord.duration.quarterLength = chord_duration # Add the chord to the sheet music sheet_music.append(chord) else: # Create a single note object note_obj = note.Note() note_obj.pitch.midi = 40 + int(5) # Assuming standard guitar tuning note_obj.duration.quarterLength = 1 # Customize the duration based on your tab notation # Add the note to the sheet music sheet_music.append(note_obj) return sheet_music # Example usage tab = """ e|------3--5--7-----5--3------------------| B|--------------------------5--7--5--------| G|--------------------------------7--4--2-| D|----------------------------------------| A|----------------------------------------| E|----------------------------------------| """ sheet_music = tab_to_sheet(tab) sheet_music.show()

This is what I got so far (using ai) idk if this is of any help?

I ran it on pycharm after installing pip music21 and python (you can probably tell that I have no idea what I am doing)

Thank you, I'm pleased you're finding them helpful. I am planning to make a video about working with chords. I haven't worked very much with midi but it is a supported format so I will look into it.

Certainly. That's quite easy to do; I can make a video that goes into more detail about working with musicxml.

Thanks, I'm glad you're enjoying them. To do that, you can follow a similar approach to the example in this video; use recurse and then iterate to extract each part object. I hope this helps.

I'm glad this is helpful

Sure; to do that you can use converter.parse() to convert supported file formats, such as musicXML into a Score. I plan to make a few videos about analysis.

@@codemeowstro1701 It would be sooo great! Please do it :D The way you explain things is so much easier for me than reading about this :)
