Using python please, thanks!

EXERCISE 4: Notes Synthesis Note Frequency (Hz) A 220 0 B 0 C# 220 - 2 220-21 220-21 C# F# D E A For this exercise we will synthesize 8 notes for A-Major scale shown above D E 220-25 220.23 F# F# G# 220-21 440 . Using the generate_sine() function, synthesize 8 notes that make up A-Major scale. Each note should last 1 second. For each note, use sampling rate fs = 8000 and amplitude = 1 Once all 8 notes are constructed, concatenate them into a single 10 array, Play the concatenated notes using simpleaudio and write it into an audio file with name "a_major_scale wav" EXERCISE 5: Chord Synthesis Note Frequency (Hz) 220 Chord 2 Chord 4 0 Chord 6 0 B 0 Chord 1 - A+CH Chord 2.8.0 Chord 3 - CNE Chord 4-DF Chord S.E.G# Chord 6 = F#+A CH A B C# D E F# GH A D 220-21 220-214 220-28 220-2 220 - 21 220-21 Chord 1 Chord 3 Chord 5 E F# # G# 440 For this exercise, we will expand upon exercise 4 to synthesize music chords - Le set of pitches consisting of multiple notes . For example, a chord could be A + B or B C# + D, etc Generate 6 chords as shown above figure - each chord consists of addition of two notes and should last for 1s with sampling frequency of 8000Hz. Make sure you normalize the amplitude of the chord between-1 and 1 to be compatible with simple audio standard Concatenate 6 chords into a single 10 array and write into audio file with a name "6_chords way
