1. What is Music Part Writing Interval Calculation?

Music part writing interval calculation determines the distance between two musical notes measured in semitones. This is essential for proper voice leading, harmonic progression, and creating musically satisfying compositions.

2. How Does the Calculator Work?

The calculator uses the interval formula:

Where:

• \( Note1 \) — First MIDI note value (0-127)
• \( Note2 \) — Second MIDI note value (0-127)

Explanation: The calculation measures the exact number of semitones between two MIDI notes, which is fundamental for understanding musical intervals in part writing.

3. Importance of Interval Calculation

Details: Accurate interval calculation is crucial for proper voice leading, avoiding parallel fifths/octaves, creating smooth melodic lines, and maintaining proper harmonic relationships in multi-part compositions.

4. Using the Calculator

Tips: Enter valid MIDI values (0-127) for both notes. The calculator will compute the interval in semitones between Note2 and Note1.

5. Frequently Asked Questions (FAQ)

Q1: What are MIDI note values?
A: MIDI note values range from 0-127, where middle C is typically 60. Each integer represents one semitone.

Q2: How do intervals relate to music theory?
A: Intervals define the distance between pitches and form the building blocks of scales, chords, and harmonic progressions.

Q3: What are common intervals in part writing?
A: Common intervals include perfect intervals (4th, 5th, octave), major/minor intervals (2nd, 3rd, 6th, 7th), and the tritone.

Q4: Why avoid certain intervals in part writing?
A: Parallel perfect intervals (5ths and octaves) are typically avoided as they can weaken the independence of voices in multi-part writing.

Q5: How does this help with voice leading?
A: Calculating intervals helps composers maintain proper voice leading by ensuring smooth melodic motion and appropriate harmonic spacing between parts.
