Question

What is harmonic progression?​

Answer 1

Answer:

a series of chord changes forming the underlying harmony of a piece of music.

Answer 2

Answer:

A sequence is in H.P, if the reciprocals of its terms form an A.P.

Step-by-step explanation:

General form of H.P is $\frac{1}{a},\frac{1}{a+d}+\frac{1}{a+2d}...\frac{1}{a+(n-1)d}$ where a is the first term and d is the common difference.

Few properties of H.P :-

a, b, c are in H.P $\rightarrow\;\frac{2}{b}\;=\;\frac{1}{a}+\frac{1}{c}$

nth term of a H.P is given by $\frac{ab}{b+(n-1)(a-b)}$ where a and b are the first two terms of H.P.

If mth term of H.P is n and nth term of H.P is m then $T_r\;=\;\frac{mn}{r}$.
