Hot Pans - Stockholm Steelband

Quadrophonic Pan

The recently invented quadrophonic pan covers the largest tonal range of all regular steel pans. The four drums accommodate altogether 36 notes, ranging from B2 to Bb5. The notes are distributed over the drums in a chromatic sequence from left to right, drums numbered 1 to 4 (see figure), beginning with B2 in drum 3. In this way, the smallest tonal interval residing in the same drum will be a major third. The notes in this interval are placed beside each other, resulting in one augmented chord for each drum: C# maj, D maj, D# maj, and E maj, left to right.

Overview of the Quadrophonic pan

Measures for the Quadrophonic pan

Data for the quadrophonic pan was gathered during a research trip to Trinidad in March 1990. Some measurements are still missing, especially the note sizes. The measurements given here are extrapolated from the same notes in guitar pans and double seconds. There is no existing pan with these note sizes, but the real measures should not deviate too far from what is given here. Tangential measures for outer notes are not given, because these are not relevant for panmaking.
