UKulele Tuning Frequencies Webhook | Uke Tune Along API

Instant UKulele tuning targets via a GET webhook (Uke Tune Along API + online tuner)

This n8n workflow exposes a UKulele Tuning Frequencies webhook that fetches accurate string notes and target frequencies from the Uke Tune Along API, optionally using your own A4 reference. Call it from your app, browser, or HTTP client and get back a structured JSON response plus an online tuner link—ready to drive your next tuning experience.

What this workflow does

• Receives a GET webhook request at /ukulele-tuning with optional query parameters such as tuning and a4.
• Calls https://uketunealong.com using an HTTP Request node to fetch the requested ukulele tuning (default: standard).
• Applies an A4 reference frequency (default: 440 Hz) by passing the provided a4 value to the API.
• Validates and formats the API response: on success, it returns notes and target frequencies for each string and includes the online tuner URL.
• Returns JSON with appropriate HTTP status codes, including structured error details for invalid/unknown tunings, and a 502 fallback if the service response is unexpected.

Use cases

• Build a tuning assistant page that updates targets in real time when a user selects standard, low-g, or baritone.
• Enable SaaS operators to embed an ukulele tuning frequencies API into existing customer onboarding or practice tools.
• Automate practice sessions by generating the correct targets whenever a musician changes tunings or A4 calibration.

Technical details
