1. What is Solfege Interval Calculation?

Solfege interval calculation determines the musical distance between two notes in the solfege system (Do, Re, Mi, Fa, Sol, La, Ti). It helps musicians understand and identify intervals by ear and in music theory.

2. How Does the Calculator Work?

The calculator uses solfege steps to determine intervals:

Where:

• Do = Position 1
• Re = Position 2
• Mi = Position 3
• Fa = Position 4
• Sol = Position 5
• La = Position 6
• Ti = Position 7

Explanation: The interval is calculated by counting the number of steps between the starting and ending solfege notes.

3. Importance of Interval Calculation

Details: Understanding intervals is fundamental to ear training, sight-singing, music composition, and improvisation. It helps musicians recognize and reproduce musical relationships.

4. Using the Calculator

Tips: Select your starting and ending solfege notes from the dropdown menus. The calculator will display the interval name and semitone count.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between solfege intervals and semitones?
A: Solfege intervals count scale steps (Do-Re-Mi), while semitones measure exact pitch distance (each semitone = 1/12 of an octave).

Q2: Why does Do to Fa count as a fourth when it's only 3 steps?
A: Intervals are inclusive - counting both the starting and ending notes (Do=1, Re=2, Mi=3, Fa=4).

Q3: Are all seconds equal in semitones?
A: No - Do-Re is 2 semitones (major second), but Mi-Fa is 1 semitone (minor second).

Q4: How can I use this for ear training?
A: Practice singing intervals using solfege to internalize their sound and relationship.

Q5: What about chromatic notes?
A: This calculator uses diatonic solfege. For chromatic alterations (like Fi or Ra), additional calculations would be needed.
