answer:This could be due to a few reasons. Some singers may feel more comfortable singing in a lower register, so they may choose to sing the music an octave lower than written. Additionally, some songs may sound better in a lower key or octave for the singer's voice. However, it's always best to stick to the written music and follow any indications or instructions given by the composer or arranger. If there is no indication to sing an octave lower, it's important to practice singing in the correct octave to accurately perform the piece as intended.

answer:Some singers may choose to sing an octave lower in their own arrangements for stylistic reasons. Singers may prefer the lower octave for the tone or emotion it brings to the performance. It could also be a deliberate choice to create a different interpretation of the song. However, it's important to note that changing the octave of a melody can alter the overall feel and sound of the song, so it should be done thoughtfully and purposefully. It's always best to stick to the written music or make clear arrangements if changes are going to be made. In a professional context, singers should communicate any changes to the arrangement with their fellow musicians to ensure a cohesive performance.

answer:You are correct that singing in a different octave typically does not change the mood or feeling of a song in the same way that singing in a different key would. However, the choice to sing in a different octave could still have an impact on the overall sound and character of the performance. For some singers, singing in a lower octave may make the song feel more grounded or intimate, while singing in a higher octave may bring a sense of lightness or brightness. These subtle differences in tone and timbre can influence the emotional impact of the performance, even if the melody itself remains the same. Ultimately, the decision to sing in a different octave is a personal artistic choice that can vary from singer to singer. As long as the performance is authentic and communicates the intended emotion or message of the song, the specific octave chosen may not be as important.

answer:Singing in a contradictory voice, sometimes referred to as vocal dissonance or vocal contrast, involves intentionally using a voice that contrasts with the typical or expected vocal style for a particular genre or song. This technique can create a unique and unexpected sound that can add depth, complexity, and interest to a performance. Some reasons why a singer may choose to sing in a contradictory voice include: 1. Adding emotional depth: Singing in a contradictory voice can create a sense of emotional complexity and depth by juxtaposing different vocal qualities. This can enhance the overall emotional impact of the song and engage the listener on a deeper level. 2. Creating contrast: Contradictory voices can create contrast and dynamics within a performance, adding interest and keeping the listener engaged. By switching between different vocal styles, the singer can highlight different aspects of the song or convey different emotions. 3. Highlighting symbolism or themes: Using a contradictory voice can also be a deliberate artistic choice to highlight themes or symbolism within the song. The contrast between the different vocal styles can emphasize certain aspects of the lyrics or message of the song. Overall, singing in a contradictory voice can be a powerful artistic choice that adds depth, complexity, and interest to a performance. It can help the singer convey emotion, create contrast, and highlight themes within the song, making the performance more compelling and memorable for the audience.
