This is a transcription of the wonderful performance of Jobim's Bossa nova-standard "One Note Samba" by Caterina Valente and Dean Martin on The Dean Martin Show. This particular TV appearance greatly helped exposing the music genre to the broader North American audience.
For guitarists, this is a great introduction to Bossa nova guitar playing - both to the standard picking rhythm and to some typical chord voicings used in the genre. This is such a playful recording, and it makes this quite complex music appear to seamless to play.
The Portuguese title "Samba de Uma Nota Só" literally translates to "samba of one note only", referring to the melody note sung throughout the first 8 bars of the verses (in this key of A♭ Major, it is the note E♭). In the common solfége / solfejo system, that note happens to be named "so(l)", which may be a musical wordplay by the composer.
