TTBB

In musical choral notation, TTBB denotes a four-part men's chorus. Its configuration is Tenor 1, Tenor 2, Bass 1 (Baritone), Bass 2.

The Tanunda Liedertafel 1861 employs this method of notation in their music.

Typically (but not always) the 1st Tenor part is the melody, with the other parts as harmony(s).

The Tanunda Liedertafel in parts are expressed as; 1st Tenor, 2nd Tenor, 1st Bass, 2nd Bass.

The way traditional German music notation is expressed (with two staves): T1 - treble clef 8va - up stem, T2 - treble clef 8va - down stem, B1 - bass clef - up stem, B2 - bass clef - down stem.

The above may not be true for some recently written (composed) music, however writers make it is easy to see which part sings their respective pitch. For example, T1 and B1 the highest pitch on each stave. Most of the time, this occurs where T1(B1) and T2(B3) are singing at the same time (in time).

Sometimes (rarely) the melody part (or lead) is sung as a solo, with the choir singing the harmony parts (support or backing vocals). (The recent rendition of The Holy City sung by the Liedertafel demonstrates this - though no audio recording of this exists)
