Highway to Hell - No Vocals - Tuned to A415.30 (Full Step Down)

Tuning a full step down from A440 Hz means that you’re lowering the pitch of each string on your guitar by two semitones, or a whole tone. This results in the standard EADGBE tuning being adjusted to DGCFAD. Here’s how the tuning changes for each string:
• E (6th string) tunes down to D
• A (5th string) tunes down to G
• D (4th string) tunes down to C
• G (3rd string) tunes down to F
• B (2nd string) tunes down to A
• E (1st string) tunes down to D
Here’s the calculation for the new A4 frequency when tuning down a full step:
A4new= (122)2A4standard= (1.05946)2440 Hz≈415.30 Hz
This tuning is often used to achieve a deeper, heavier sound, and is popular in genres like rock and metal.
