Parallel Intervals Checker for MuseScore Studio 4

Parallel Intervals Checker is a MuseScore plugin that identifies and highlights parallel intervals such as parallel fifths, octaves, and hidden parallels within your music score. This tool is specifically designed to help composers and arrangers avoid the use of parallel intervals, which are often considered undesirable in traditional counterpoint. It marks consecutive fifths, octaves, and hidden parallels for easy visualization and correction.

Features

• Detect Parallel Fifths
  Identifies consecutive fifth intervals that are parallel between voices.

• Detect Parallel Octaves
  Detects consecutive octaves that occur in parallel between voices.

• Detect Hidden Parallels
  Identifies hidden parallels (either fifths or octaves) that occur between two notes in ascending order.

• Coloring & Marking
  Automatically colors the notes and adds staff text annotations to mark the parallel intervals for easy identification and correction.

• Customization
  The plugin allows users to choose:

  • Which intervals to detect (parallel fifths, octaves, or hidden intervals).
  • Whether to use only coloring or coloring with text markings.
  • Custom color settings for each interval type (fifths, octaves, hidden intervals).
  • Dry run mode (no markings are applied, just a check).
  • Cleanup before run to remove old markings from previous runs.

• Compatibility
  Fully compatible with MuseScore Studio 4, with support for its latest versions.
