1. Original Guitar Recording: George Harrison recorded his original guitar solo normally, in the forward direction.
2. Tape Manipulation: The master recording tape of the guitar solo was physically cut into sections and then reassembled in reverse order, essentially flipping the solo backwards.
3. Synchronizing with Original Track: The reversed solo was then synchronized with the original forward-played track. This required precise editing to match the timing and placement of the notes.
4. Adding Effects: Additional effects were added to the reversed solo to enhance its distinctive sound. These included echo, reverb, and panning to give it a more ambient and ethereal quality.
5. Mixing: The reversed solo was carefully mixed with the main track, balancing its volume and placement to create the desired effect.
By combining these steps, the Beatles created the iconic reverse guitar solo in "While My Guitar Gently Weeps," making it a memorable and innovative moment in music history.
