Escalas con Bemoles: demostración en el resto de las escalas

Introduction and Overview

In this class, the instructor will demonstrate how to apply the rules for constructing scales with flats. The previous class discussed the rule that states a new flat is added in the fourth degree of each scale. Additionally, it was mentioned that one of the tetrachords from the previous scale is identical to one of the tetrachords in the new scale.

Constructing Scales with Flats

  • In each scale, the fourth degree will introduce a new flat.
  • The relationship between scales can be observed by comparing their tetrachords.
  • The scale being deduced now is Cb major, where Cb is the new flat introduced in the fourth degree.
  • All scales start and end on the same note. The Cb major scale consists of two tetrachords - Cb Db Eb F and G Ab Bb Cb.
  • The second tetrachord of Cb major is identical to the first tetrachord of F major, confirming our rule.

Deducing Other Scales with Flats

  • The next scale to deduce is Eb major, where Eb becomes the new flat in its fourth degree.
  • Continuing this pattern, we deduce Ab major with Ab as its new flat in the fourth degree.
  • Following this sequence, we deduce Db major with Db as the new flat in the fourth degree.
  • The final scale deduced is Gb major, with Gb as the new flat in its fourth degree.

Conclusion and Next Steps

This video covered all scales with flats and demonstrated how to deduce them using two simple rules. In future videos, chords formed within each scale will be explored. It is important to note that the order of tones and semitones observed in scales with sharps also applies to scales with flats.

  • The rules discussed in this class apply to all scales with flats, confirming the consistency of tone and semitone patterns.
  • The focus of this class was on two new constants for constructing scales with flats, but it does not negate the constant order of tones and semitones within tetrachords.

Timestamps are approximate and may vary slightly.

Structure of Tones and Semitones

In this section, the instructor discusses the structure of tones and semitones in scales.

Tetrachords in C-flat Major Scale

  • The instructor explains that if we examine the two tetrachords of the C-flat major scale, we can observe the pattern of tones and semitones.
  • In C-flat to A-flat, there is no semitone between C-flat and D-flat as expected in a desired scale.
  • Instead, starting from S (S for "semitone"), there is a whole tone between S and D-flat.

Tones and Semitones in Other Scales

  • The instructor mentions that if we apply the same analysis to other scales, we will see a consistent pattern of tones and semitones.
  • Using the example of the M minor major scale, they point out that there is a whole tone between E-flat and F, instead of a semitone as expected in a natural scale.

Consistency Across All Scales

  • The instructor emphasizes that this pattern holds true for all scales.
  • They encourage viewers to verify this by doing the intellectual exercise themselves or referring to graphical representations provided in the video.

Analysis of Tetrachords in Other Scales

In this section, the instructor continues discussing tetrachords in different scales.

Tetrachord Analysis - M minor Major Scale

  • The instructor examines the first tetrachord (E-flat to A) of the M minor major scale.
  • They note that there is a whole tone between E-flat and F, as well as between F and G. This confirms the consistent pattern observed earlier.

Conclusion and Next Steps

In this final section, the instructor concludes the class and provides some closing remarks.

Verification of Tones and Semitones

  • The instructor reiterates that viewers can verify the pattern of tones and semitones in different scales by doing the intellectual exercise themselves.
  • They assure that everything will be in order when checked.

Closing Remarks

  • The instructor concludes the class and hopes that it has been helpful to the viewers.
  • They wish everyone success on their musical journey.

This is a summary of selected sections from the transcript.

Video description

En esta clase educativa, se explora detalladamente la formación de escalas con bemoles, demostrando cómo se cumplen reglas y constantes en este proceso. A continuación, se presenta un resumen de las secciones clave: Sección 1: Escalas con bemoles y reglas de formación Regla del cuarto grado: A los cuartos grados de cada escala, se les agrega un nuevo bemol. Relación entre tetracordios: El primer tetracordio de una escala es idéntico al segundo tetracordio de la escala anterior. Ejemplo práctico con C♭ mayor: Se deduce la escala de C♭ mayor aplicando estas reglas. Nota importante: Todas las escalas comienzan y terminan en la misma nota bemol. Sección 2: Ejemplo práctico con C♭ mayor Desglose de la escala: La escala de C♭ mayor se analiza en términos de tonos y semitonos. Relación con otras escalas: Se explora cómo el cuarto grado de C♭ mayor indica la siguiente escala, estableciendo una relación continua. Sección 3: Conclusiones y próximos pasos Resumen general: Se abordan todas las escalas con bemoles, demostrando cómo deducirlas mediante reglas sencillas. Validación de reglas: Se destaca que las reglas de tonos y semitonos se aplican consistentemente en las escalas mayores con bemoles. Próximos temas: Se adelanta que los siguientes videos explorarán los acordes formados en cada una de las escalas. Sección 4: Estructura de tonos y semitonos en escalas Análisis de la escala de C♭ mayor: Se examina la estructura de tonos y semitonos en la escala de C♭ mayor. Verificación en otras escalas: Se realiza un análisis similar en otras escalas para confirmar la consistencia del patrón. Sección 5: Ejemplo con la escala m mol mayor Análisis específico: Se estudia la escala m mol mayor, analizando su estructura de tonos y semitonos. Invitación a la verificación: Se anima a los espectadores a realizar ejercicios similares con otras escalas. Sección 6: Conclusión y despedida Agradecimiento: Se agradece a los espectadores por asistir a la clase. Animación a seguir aprendiendo: Se alienta a los espectadores a continuar sus estudios musicales y se les desea éxito en su viaje. Este video proporciona una guía detallada sobre la formación de escalas con bemoles, con ejemplos prácticos y la validación de reglas fundamentales. ¡Nos vemos en la siguiente clase!
