Interval Calculator MCP. Know the exact math and theory behind every note combination.

Interval Calculator MCP helps musicians and theorists determine the exact relationship between musical notes. You can calculate raw semitone distances, figure out if an interval is consonant or dissonant, and find the precise frequency (in Hz) of any note using standard tuning systems.

The Manual Pain of Music Theory

Right now, if you need to know the relationship between two pitches, you're either cross-referencing dense textbooks or running through multiple online calculators. You calculate the distance in semitones, then you check a second chart for the formal name (Major 3rd?), and finally, you have to manually look up the precise frequency for your synthesizer patch, constantly copy-pasting values between tabs.

With this MCP, all that manual cross-referencing vanishes. You ask your agent for the interval data, and it returns a single source of truth: semitones, formal name, stability classification, *and* the correct Hz frequency—all in one step.

Interval Calculator MCP Provides Full Pitch Analysis

You stop having to juggle three different kinds of data points: raw number distances from `calculate_semitone_distance`, musical labels from `identify_interval_properties`, and physical Hz values from `calculate_note_frequency`. The system gathers it all for you.

The result is immediate, comprehensive, and always accurate. It’s the single source of data every composer or theorist needs.

What Interval Calculator MCP does for your AI

Need to know exactly how far apart two notes are? This MCP handles all the math for music theory. You don't just get a number; you figure out the musical character—is it a perfect fifth, or something more unstable? It determines interval qualities and stability like consonant versus dissonant. Plus, if you need the actual physical vibration frequency of a note in Hz, this MCP calculates that too, supporting both A4=440Hz and A4=432Hz tuning standards.

Instead of flipping between separate calculation sheets or searching dense theory texts, your agent handles all these calculations instantly. Vinkius hosts this MCP so you connect once through any compatible client and get access to powerful tools like this one. It's pure, reliable musical data at your fingertips.

Frequently asked questions about Interval Calculator MCP

How do I find the semitone distance using Interval Calculator MCP? +

Use the calculate_semitone_distance tool and provide two notes along with their octaves (e.g., C4, G4). It returns the raw numerical difference in half steps.

Does Interval Calculator MCP handle different tuning standards? +

Yes. The calculate_note_frequency tool supports determining note frequencies using both A4=440Hz and A4=432Hz tuning systems, giving you versatile data.

What is the difference between calculating distance and identifying properties? +

Calculating distance (calculate_semitone_distance) gives a raw number (e.g., 7). Identifying properties (identify_interval_properties) tells you what that interval means musically, like 'Perfect 5th,' and whether it's consonant.

Can Interval Calculator MCP give me the frequency for two notes? +

You must calculate them separately. Use calculate_note_frequency once for each note you want to analyze, ensuring you specify the correct tuning standard (432Hz or 440Hz).

Does this MCP work with any AI client? +

Since it's an MCP hosted on Vinkius, your agent can connect to it using any compatible client application that supports the Model Context Protocol.
