Frequency just below 6 kHz, good enough for COFL.

Very interesting transitional form with NO SILENT BREAK. Tick and maximum frequency are a shade high for COFL. Top almost pointed = intermediate. Overall shape is intermediate between PSFL and the smooth unbroken COFL standard from the Southern Rocky Mountains. Lack of break tips the scale toward COFL.

COFL-like intermediate. Frequency barely above COFL standards. Middle note is rather faint for COFL, but it is still louder than the tick.

Close to COFL, the absence of a break being the main deficiency. Sounds very similar to some of the COFL standards.
