Parsing

metric that takes rhythm into account, levenshtein of both pitch and start, maybe also duration, differently weighted

[feature] use double barlines to split into finer sub-sections
[feature] color each bar by metrics
- note density
- note count
- variance of pitch, duration, ...
- ratio of pauses to notes
- ...
[feature] color each bar/chord by scale
- key detection: https://tonaljs.github.io/tonal/module-Detect.html#~scale
[performance] make clustering more performant by not reclustering on threshold change
- or at least debounce
[performance] only remap colors when changing scale, do not recompute DR etc!
[feature] allow coloring compressed by sections
[feature] clustering with brightness for within-cluster similarity
- colors for each cluster
- for bars within each cluster, assign brightness by leaf ordering

show note color legend in tree when notes are shown
player
- [bug] seems one bar ahead for some pieces
make showTrailingRests global
show meter and tempo changes in tracks view
- also draw ticks for bars numbers
- Add tempo curve to tracks view
- And time signature labels
metronome, mute player (or just gain slider)
- easy with alphatab
tuning pitches parsed incorrectly when showing staff and tab
expand repetitions in XML for consistent display over all views
[feature] PDF export of colored sheet music (lib/pdf.js)
- [bug] export currently sometimes only exports part of the score, cutting of at some width and height
- allow paged mode (currently messes up coloring)
- fix tab notes not being exported correctly, see opensheetmusicdisplay/opensheetmusicdisplay#1371
[cleanup] remove smui
- view menu
- player
- keep for modals

detect instrument and select note rendering automatically? or suggest and let user apply/cancel
[feature] drum note encoding

[readability] make borders around highlighted things thicker, eg in tree view
score
- [bug] avoid colored rects overlapping the ones in the next bar row by finding the next larger y and taking the min(yBottomCurrentRow, yTopNextRow-10)
- bounding boxes are wrong sometimes
- does not work for some musicxml files
- [feature] animate scrolling a bit, maybe ease-in
compressed
- should scroll to show current bar in center or left
compact
- [bug] compact view does not work when another than the first track selected
  - leading rests causes it, probably wrong measure times
- [readability] repeated notes should also work for repeated chords
- colored line above section/motif, to better see when the same color comes twice in a row, where the new part starts
tab view
- [feature] render guitar tabs with alphatab
  - integrate alphatab and render an example
  - render musicxml or .gp
  - colorize bars
  - highlighting and interaction
  - allow to toggle notes (to only show tab)
  - allow to make bars same width CoderLine/alphaTab#1183 (comment)

[concept] two-dimensional color map for two metrics at once, e.g., rhythmic and melodic similarity
[feature] allow playing only current selection/loop it
[feature] allow to select multiple consecutive bars
- selection of two consecutive sequences of bars, comparison of two selections
allow to see multiple instruments at the same time and compare them
allow to manually assign colors to selections to overwrite coloring, apply to other occurrences automatically
include metrics as a coloring source
try to add section labels to compressed as well
get colors from compressed blocks: each block that is repeated or in between reps gets its own color
new note encoding
- drums
- staff
support 7-string guitar, 4-string bass, etc
- check tuning pitches to get the number of strings, then compute bbox of measures from that?
- sheet
- score
drum playback
- fix drum sound map
- allow to use custom map from pitch to sound
allow printing colored sheet music
[feature] segment into motifs, riffs
- most common ngrams, largest first
