More Details Connect to Claude

An essential tool for musicians and theorists to calculate the distance between notes in semitones, identify interval qualities (such as Major 3rd or Perfect 5th), determine stability (consonant vs. dissonant), and compute precise frequencies in Hz using A4=440Hz or A4=432Hz tuning standards. Use calculate_semitone_distance for raw distance, identify_interval_properties for musical character, and calculate_note_frequency for frequency calculations.

3 tools expose this connector's capabilities to your AI agent.

identify_interval_properties

Describe the musical character and identity of an interval

calculate_note_frequency

Determine the physical vibration frequency for a specific note

calculate_semitone_distance

g., "C4") and end note (e.g., "E4") and returns total semitones moved. Find the raw numerical distance between two pitches in semitones

See how to talk to your AI agent using Interval Calculator.

What is the distance in semitones between C4 and G4?

The distance between C4 and G4 is 7 semitones.

Tell me about the interval between D4 and F4.

The interval from D4 to F4 is a Minor 3rd, which is classified as Dissonant. Its inversion is an Augmented 6th.

What is the frequency of A4 using 432Hz tuning?

The frequency of A4 with a 432Hz tuning standard is 432.0 Hz.

Use the `calculate_semitone_distance` tool by providing the starting note and the ending note (e.g., 'C4' and 'E4'). It will return the total number of semitones between them.
