Low pitched tones tend to be more difficult because they can have their low harmonics suppressed. Short notes or tones with time- varying pitch can give problems, as do tones with inharmonic partials, like the piano. You might try a harmonic pattern matching method such as the two-way mismatch method. It is written up in R. C. Maher and J. W. Beauchamp (1994). "Fundamental frequency estimation of musical signals using a Two-Way Mismatch procedure", J. Acoust. Soc. Am., Vol. 95, No.4, pp.2254-2263. and it is implemented in the SMS and SNDAN musical sound analysis/ synthesis packages. For piano tones, I know that Anssi Klapuri, who has done much work on music pitch detection, has specially treated that case. Google will find him quickly.
