examples my students have come up with for Sonny's Blues include:

• While family relationships are often filled with misunderstandings,healing can begin once one attempts to understand. 
• Even within the depths of drug addiction there are sections of a person that cannot be destroyed, and can even lead to redemption. 
• Living in poverty can cause people to seek to escape their circumstances through drug use but passion cannot be destroyed. 

To turn this into a thesis statement for an essay, you can make it a structural critique discussing how the author employ's literary strategies to build the theme:

• In Sonny's Blues, James Baldwin effectively uses the first person narrative style along with complex characterization to develop his theme that while family relationships are often filled with misunderstanding but when understanding is sought these relationships can be healed.

It can also be presented as a thematic critique which implies an aesthetic value judgement:

• Some critics/readers suggest that Sonny's Blues is a story about the impact of drug abuse and the struggles with recovery; however, closer examination reveals a complex theme about family relationships and how these relationships are often strained, seemingly beyond repair.

In James Baldwin's "Sonny's Blues," the theme of family relationships runs throughout the story. Thematically, we also see reference to the artist and his art. While the family relationship between the brothers is a strong thematic element that impacts Sonny as a musician and a person, what draws me more is the concept of the struggle between the artist and his art. While there is a great deal of controversy between the brothers (which cannot be ignored), the struggle is at the core of understanding Sonny, the artist. 

Sonny has certainly taken a dark and difficult road in his life. Substance abuse seems to have dogged his every step. And while his brother has been able to dodge the same fate by getting an education and moving out of the old neighborhood, his desire to leave his past behind has robbed him of the ability to see how the past has affected and haunted Sonny. It is completely understandable in that Sonny's brother wants what is best for his sibling, the brother he promised their mother he would watch out for. 

Sonny represents those members of society that struggle to find their place when that place is not a part of the mainstream. Music is Sonny's life. The "blues" are not just what he plays, but also what he experiences based on his life choices and his struggle to pursue music with those choices. 

The question of what Sonny wants, what he lives for, comes up in a letter he writes to his brother from prison. Sonny is ashamed; he feels as if he has disappointed everyone. He cannot even verbalize how he has ended up at such a terrible place in life. However, he shows how much music means to him by assuring his brother that it is not the reason for his current situation:

I don't want you to think it had anything to do with me being a musician. 

The brothers keep in touch. When Sonny gets out of prison, he asks his brother to drive him past the old neighborhood. This demonstrates how closely tied Sonny is to the past—a past of suffering that still affects him.

His brother notes, as the taxi goes by the old neighborhood, that they pass the "killing streets of our childhood."

Sonny's brother can only see the world he is in and wish that world for Sonny. However, Sonny has not left the old neighborhood—not as his brother has—and he does not know how to survive in his brother's world. The primary reason may be because his brother's life has no room for Sonny, his music and what drives that music. Music is at the core of Sonny's existence.

Sonny tells his brother:

—well, yes, sure, I can make a living at it. But what I don't seem to be able to make you understand is that it's the only thing I want to do...I think people ought to do what they want to do, what else are they alive for?

Sonny tells his brother that in the pursuit of music—with trueart—one must suffer. This is not an experience his brother understands. Sonny is aggravated because he believes his brother wants Sonny to suffer in a way his brother understands, but it is not Sonny's way. Sonny thinks the drugs may have helped him to survive his suffering, with the [illusion] of control over his life.

Ultimately, it is only after Sonny's brother hears Sonny play that it all seems to make sense. In Sonny's music there is sorrow born of suffering, but there is also a freedom—freedom born out of Sonny's music for all those who have suffered.

If I were to write about "Sonny's Blues" about the theme of the relationship between a man (or woman) and his art, I would concentrate on the contradiction art creates in the artist. With Sonny, suffering is necessary in order for him to play; but at the same time, it is only through his music that he experiences any freedom (however temporary) from his suffering. And that for those not living in his world, they cannot understand it, nor should they try to change it. It is futile because these elements are an integral part of Sonny's music and his life.

My thesis statement would be:

In James Baldwin's "Sonny's Blues," suffering is a part of the human condition. Sonny suffers from addiction, incarceration and his brother's lack of understanding; but the very things that cause Sonny to suffer are the same things that allow him to create music in order to transcend that suffering.

Hi!  It's me again.  I recently suggested to you some of the themes in "Sonny's Blues," and I think you liked them since my reply got 5 stars.

To write a thesis statement, I suggest using one of the themes as a basis.

Theme a: What it was like to grow up in Harlem.

Thesis Statement a: "Sonny's Blues" describes the almost impossible task of growing up as a black male in Harlem in the 1930's and 1940's.

Theme b: The different ways that people attempt to escape the ghetto: Sonny tries music and drugs, his brother tries to go "straight" and becomes a middle-class school teacher.

Thesis Statement b: "Sonny's Blues" describes the different ways that people attempted to escape the Harlem ghetto in the 1940's; some tried music and drugs, while others attempted to assimilate into middle-class society.

Theme c: The complex relationship between two brothers

Thesis Statement c: "Sonny's Blues" describes the complex relationship between two brothers.  Throughout much of the story, Sonny's older brother is reluctantly thrust into a parental role; at the end, it is Sonny who teaches his brother a lesson.

Theme d: The way a musician expresses his feeling through music

Thesis Statement d: In "Sonny's Blues," we find a masterful description of how a musician can express his feelings through his music.

Good luck!

With the brother of Sonny as narrator, Baldwin affords the reader not only insight into the character of the narrator, but also insight into the character of Sonny as together they unite in their suffering from having lived in the "killing streets" of Harlem.  Thus, the pain of the narrator in his recall of their past, as well as his pain at having lost his daughter Gracie, unites to the artistic suffering of Sonny who has been misunderstood by the narrator.  For, it is their passage from the past to the present together that Sonny and the narrator/brother come together in understanding in the nightclub where the narrator realizes,

Freedom lurked around us and I understood, at last, that he cold help us to be free if we would listen, that he would never be free until we did.

Thus, Baldwin's use of the brother as narrator denotes the theme of brotherhood in suffering, tying together the "blues" of all experiences:  heroin, death, religion, and music. 

For, while the tale of how we suffer, and how we are delighte, and how we may triumph is never new, it always must be heard.  There isn't any other tale to tell, it's the only light we've got in all this darkness.

The narrator, who is brother to Sonny, becomes the listener to "Sonny's blues," and, in so doing, he connects with Sonny, thus affoding Sonny freedom from his suffering, as well.

When we think of point of view in literature, there are three main types that are used. Clearly, in this excellent short story, the point of view Baldwin chose to use is first person, which is when the story is told by a character in the story itself, who is part of the action of the story and narrates everything from his or her perspective, as indicated by the use of "I." To consider what thesis statement you can use, you need to consider the aspects of this point of view.

First person point of view really establishes a sense of rapport between the reader and the narrator. We see everything through their eyes, and understand their motives, thoughts, feelings and actions. Therefore, this story, which focuses so much on how the narrator changes in his feelings towards his younger brother, the point of view really helps emphasise this aspect. You might consider a thesis statement that illustrates this point, such as:

The first person point of view in "Sonny's Blues" helps emphasise the change in the character of the narrator towards his younger brother.

This would allow you to identify how the narrator starts off not understanding Sonny and judging him and then how he changes, until the end of the story, where his act of buying drinks for his brother and the band symbolises his understanding and empathy of the Sonny's difficulties and situation.
