Identify the false statement:
on the synthesizer, timbre and volume depend on the waveform.
synthesis refers to creating sounds electronically from electronically generated waveforms.
the synthesizer generates sounds electronically.
synthesizers have always had a well-established presence in standard ensembles.

Synthesizers have always had a well-established presence in standard ensembles.

Explanation:

Synthesizers play a key role today, either to simulate other instruments (piano, saxophone, strings, drums, etc.) or to create new sounds. In fact, they are one of the most widely used musical instruments in the pop music industry. Unlike most musical instruments, which are based on acoustic principles, synthesizers are completely electronic instruments. Regarding the synthesizers we can say that in the synthesizer, timbre and volume depend on the waveform; Synthesis refers to the creation of sounds electronically from electronically generated waveforms and the synthesizer generates sounds electronically.

For this reason we can say that the incorrect statement is "Synthesizers have always had a well-established presence in standard sets."

including the octave, the answer would 8 notes in a major scale with one note being played twice. ex) c major scale includes: c, d, e, f, g, a, b, c

notice that c is played twice

however, if you were to ask me how many different notes are in a major scale- the answer would be 7.
