The dataset adopts a three-level difficulty classification system for sight-singing scores, covering pitch difficulty, interval difficulty, and rhythm difficulty. The specific criteria are detailed in the table below.
| Difficulty Type | Difficulty Level | Classification Criteria |
|---|---|---|
| Pitch Difficulty | Hard | pitch_range > 18 semitones |
| Medium | 12 semitones < pitch_range ≤ 18 semitones | |
| Easy | pitch_range ≤ 12 semitones | |
| Interval Difficulty | Hard | large_leap_ratio ≥ 0.1 |
| Medium | moderate_leap_ratio ≥ 0.3 | |
| Easy | Otherwise | |
| Rhythm Difficulty | Hard | triplet_ratio > 0.25 or dotted_note_ratio > 0.2 or syncopation_ratio > 0.1 |
| Medium | triplet_ratio > 0.1 or dotted_note_ratio > 0.08 or syncopation_ratio > 0.05 | |
| Easy | Otherwise |
- pitch_range: The number of semitones between the highest and lowest notes in the score.
-
Interval-related definitions: Large leaps refer to intervals
$\ge 7$ semitones (perfect fifth and above); moderate leaps refer to intervals of 3–6 semitones (minor third to diminished fifth). - Ratio calculation: Interval ratio is the proportion of the corresponding interval type to the total number of intervals in the score; rhythm pattern ratio is the ratio of the total duration of notes in the corresponding rhythm type to the total duration of the score.
- Rhythm criteria supplement: "Otherwise" for rhythm difficulty means no significant presence of complex rhythmic patterns (dotted rhythms, triplets, syncopation).
