How to use this workflow
Locate the passage
Confirm your tuning and identify the candidate pitch and register before choosing a position.
Compare the evidence
Try the phrase in two plausible positions, considering the notes before and after it rather than one isolated sound.
Save a usable reference
Write your chosen fingering as a practice arrangement. Use a verified performance view or original part if the historical fingering matters.
Worked example and evidence boundary
For a standard four-string bass, A2 can be played as the open G string plus two frets, the D string plus seven frets, or the A string plus twelve frets. In semitone arithmetic, G2 + 2 = A2, D2 + 7 = A2 and A1 + 12 = A2. These equivalent pitches do not establish identical tone or fingering. This is a tuning calculation, not a transcription.
What to verify before using the result
PitchChanger does not generate bass tablature, string numbers or fret labels. Timbre may suggest a position but separation can alter it, and different techniques can resemble each other. Leave a note uncertain when the source does not support a confident pitch; do not fill a tablature grid simply because it expects a number.
Common questions
Can I call my chosen fingering the original player’s fingering?
Only if independent evidence establishes it. A playable arrangement inferred from sound should be labeled as your practice fingering.
