Pentatonic Scale Notes Generator

Generate five distinct correctly spelled major/minor pentatonic tones from explicit tonic/mode, retaining omitted diatonic degrees and double-accidental bounds.

Description

Pentatonic collections contain five selected degrees.

Pentatonic collections contain five selected degrees. Major and minor patterns omit different degrees and require different spellings.^[1]

Enter pitch-class tonic and exact major/minor mode. Spell major degrees 1,2,3,5,6 or minor1,3,4,5,7; return names and offsets.

When to use Pentatonic Scale Notes Generator

Use Pentatonic Scale Notes Generator when you need to evaluate the supplied records under the calculation and evidence rules below. More than double accidentals fail. No octave, fingering, improvisation suitability or audio generation is supplied.

Enter the written notes, explicit grouping, pitch observations or supported chord tokens requested. Keep scientific octaves, accidentals and caller evidence consistent.

How to use Pentatonic Scale Notes Generator and understand its results

Enter the written notes, explicit grouping, pitch observations or supported chord tokens requested. Keep scientific octaves, accidentals and caller evidence consistent.
Enter tonic, mode using the field table and calculation rules, then run the tool.
Read spelledPentatonicNotes, rootRelativeOffsets. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
tonic	Tonic	string	Required
mode	Mode	string	Required

Enter pitch-class tonic and exact major/minor mode. Spell major degrees 1,2,3,5,6 or minor1,3,4,5,7; return names and offsets.

major offsets=0,2,4,7,9; minor=0,3,5,7,10

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Limitations and assumptions

More than double accidentals fail. No octave, fingering, improvisation suitability or audio generation is supplied.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Extremely large text inputs are rejected. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Blues Scale Notes Generator: Major and minor blues collections add a chromatic blue degree to different pentatonic patterns. Written degrees preserve the distinction. For a complementary task, use Whole-Tone Scale Generator: A whole-tone collection contains six pitch classes separated by two semitones. Written note letters preserve a chosen scale spelling.
