The spelling of the word "thorough bass" is quite interesting. The first word "thorough" is spelled with a "th" to indicate the voiceless dental fricative sound /θ/. The second word "bass" is spelled with two "s" due to its pronunciation as a voiceless consonant /s/ at the end of the word. However, the spelling of "bass" also helps distinguish it from the homophonous word "base", which has a different meaning. In IPA phonetic transcription, "thorough bass" is pronounced /ˌθʌr.oʊ ˈbeɪs/.
Thorough bass, also known as figured bass or basso continuo, refers to a method and notation system used in Baroque music. It involves providing a harmonic and melodic framework for the accompanying keyboard instrument, usually the harpsichord or organ.
In thorough bass, a bass line is written, typically in a staff below the treble staff, and is fully notated with all the necessary harmony and melodic information. The notation includes figures, symbols, or numerals above or below the bass line to indicate the harmonies and chords that should be played by the keyboardist. These figures represent intervals, chord inversions, and slash chords, among other notations, and provide flexibility and freedom for the keyboardist to improvise or fill in the harmonies.
The purpose of thorough bass is to create a continuous harmonic foundation, allowing for variations and ornamentations within a musical composition. It enables the keyboardist to play harmonies, chords, and counterpoint while interacting with and supporting other instrumental or vocal lines.
Thorough bass was widely used during the Baroque period, from approximately the 17th to the early 18th century. It was an essential skill for keyboardists and composers of the time, providing a means for improvising accompaniment and adding depth and richness to the overall musical texture. Today, thorough bass is studied and performed as an important aspect of Baroque music interpretation and historical performance practice.
The term "thorough bass" originated in the 17th century and refers to a method of accompanying music using a single bass line together with chords and figures. It is commonly associated with the Baroque era.
The etymology of "thorough bass" can be traced back to two root words: "thorough" and "bass".
The word "thorough" is derived from the Middle English word "thurh" or "thorh", which means "through". It evolved from the Old English word "thuruh". In the context of music, "thorough" suggests comprehensiveness or completeness. It implies a thorough understanding and execution of the bass line and accompanying harmonies.
The word "bass" comes from the Italian term "basso", which means "low" or "deep".
