This web-based tool converts musical notes into frequencies. It’s designed for users who need to identify the frequency that corresponds to a specific musical note.
What It Does:
- The tool takes a musical note (from A to G, with the option to include a ‘#’ for sharp notes) and an octave number (from 0 to 8) as inputs.
- When the user clicks the “Convert” button, the tool calculates the frequency that corresponds to the entered musical note and octave.
- It uses the MIDI note number corresponding to the input note and octave, then calculates the frequency using the formula for the equal temperament tuning system:
Frequency = Note A4 frequency * 2^((MIDI note number)/12). In this formula, the Note A4 frequency is 440Hz. - After the frequency is calculated, it’s displayed on the screen.
How to Use It:
- Open the tool in a web browser.
- Enter a musical note in the “Note” input box. The note should be a letter from A to G, and you can optionally add a ‘#’ after the letter for sharp notes.
- Enter an octave number in the “Octave” input box. The octave should be a number from 0 to 8.
- Click the “Convert” button.
- The tool will calculate and display the corresponding frequency in Hz.
Important Note: This tool uses equal temperament where A4 is tuned to 440Hz, and each note is separated by a constant frequency ratio. This is a standard in Western music but might not align with every musical tradition or tuning system. Furthermore, due to the nature of the conversion process, there might be minor inaccuracies.
