Blues Scale Notes Generator

Generate six-tone minor/major blues collection with explicitly spelled blue fifth/third, not generic chromatic aliases or promised blues harmony fit.

Description

Major and minor blues collections add a chromatic blue degree to different pentatonic patterns.

Major and minor blues collections add a chromatic blue degree to different pentatonic patterns. Written degrees preserve the distinction.^[1]

Enter tonic without octave and exact major/minor. Generate six spelled tones using prescribed letters; return names and offsets.

When to use Blues Scale Notes Generator

Use Blues Scale Notes Generator when you need to evaluate the supplied records under the calculation and evidence rules below. Double-accidental limits apply. No harmony fit, microtonal blue-note behavior or performance advice is inferred.

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

How to use Blues 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 spelledBluesNotes, rootRelativeBluesOffsets. 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 tonic without octave and exact major/minor. Generate six spelled tones using prescribed letters; return names and offsets.

minor=[0,3,5,6,7,10]; major=[0,2,3,4,7,9]

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

Output field	Meaning	Value type
spelledBluesNotes	Spelled blues notes	list of string
rootRelativeBluesOffsets	Root relative blues offsets	list of number

Limitations and assumptions

Double-accidental limits apply. No harmony fit, microtonal blue-note behavior or performance advice is inferred.

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 Pentatonic Scale Notes Generator: Pentatonic collections contain five selected degrees. Major and minor patterns omit different degrees and require different spellings. For a complementary task, use Chromatic Scale Generator: A chromatic collection includes all twelve pitch classes. Canonical sharp/flat names can differ from the written tonic supplied.
