Guzheng is more standardized, suitable for traditional court music, and its voice is softer.

The voice of cucurbit flute is sobbing, which is also in line with the style of China traditional music.

The electronic organ is a pure electro-acoustic instrument, which can imitate many sounds. However, it is not recommended to imitate piano music when matching the above two instruments. It is suggested to imitate hose music such as flute and clarinet.

Guitar depends on which guitar you choose. Acoustic guitar can be directly matched with the above instruments and appear as dubbing. If it is an electric guitar, the effect should also be considered. You can use acoustic guitar timbre+reverberation+slight delay effect, which should be good.

If you want to use guzheng and guitar as the main theme, you can re-match Liang Zhu, which is actually relatively simple. Guzheng and guitar can be used to alternate the main theme, cucurbit silk as the second voice, and the electronic piano can be played and rotated.

If you want to choose electronic organ and guzheng as the main theme, you can choose "Step by Step" and "Cloud Chasing the Moon". The cucurbit silk can still be used as the second voice, and the guitar can be played and rotated.

If you want to choose guzheng and cucurbit silk as the main theme, you can choose Zizhu Tune and so on. Guitar can be decomposed and rotated, and electronic organ can lay a sound.

The above is for reference only. In fact, the principle of choosing a tune is to look at the timbre of your guitar and electronic organ before choosing a tune. Because your guzheng and cucurbit silk are relatively monotonous and have not changed much.
