1. Straight Tone:
A straight tone refers to a vocal technique where the singer sustains a steady pitch without applying vibrato or any modulation in the tone. In other words, it's a pure, even sound without fluctuations in pitch.
2. Straight Melody:
Sometimes, "straight" can also refer to a melody or musical passage that has a relatively unornamented or straightforward rhythmic and melodic structure. Unlike embellished melodies full of grace notes or variations, a straight melody presents the tune in a simplified manner.
3. Straight Eighth Notes:
In certain circumstances, "straight" is used to indicate eighth notes played precisely on the beat, not swung or syncopated. In swing rhythms, восьмые ноты usually have slight variations, but if the music requires a more "straight" feel, the восьмые ноты would fall squarely on the subdivisions of the beat.
Context and musical style matter here, as the interpretation of "straight" might slightly differ depending on the genre and specific musical piece. If you come across the term "straight," always refer to the musical notation and musical context to understand its meaning and intended execution.
